Research depth: Expanded historical analysis. About this collection

Status: Completed/expired.

Is Executive Order 9621 still in effect? No. Executive Order 9621 completed a wartime agency transfer: the OSS ended on October 1, 1945, and the temporary State Department service ended on December 31, 1945. NARA records repeal of the underlying authority by Public Law 89-554, signed September 6, 1966; the order is not a current CIA charter.

What the order directed

The order transferred research and analysis functions to State and remaining activities to War as the wartime OSS ended. It did not itself create the Central Intelligence Agency.

Why it was signed

Truman signed EO 9621 on September 20, 1945, directing the end of the Office of Strategic Services (OSS) after World War II. The order’s general effective date was the opening of business October 1. It dealt with the disposition of existing work and personnel, not with the statutory creation of the Central Intelligence Agency two years later. Signed order.

The OSS had operated under a June 13, 1942 military order. The 1945 instrument separated its research and presentation functions from other intelligence and operational activities. An account that says Truman simply moved the entire OSS intact into the CIA skips the actual transfers to State and War. EO 9621; NARA OSS organizational history.

NARA’s agency history dates OSS abolition effective October 1 and identifies the successor services. That later official record can be checked against Truman’s clauses for the exact allocation of work. A named successor unit is not the same agency merely because it used predecessor staff. NARA RG 226.

What the text authorized

Section 1 transferred the Research and Analysis and Presentation branches, except functions carried out within Germany and Austria, into an Interim Research and Intelligence Service in the State Department. The exception is express and material: an unqualified statement that every overseas analytical unit transferred to State would be wrong. Section 1.

The State transfer included relevant personnel, records and property, with the Bureau of the Budget determining some allocations. Military staff could continue with State by mutual departmental agreement, subject to law. That is a legal transfer and coordination mechanism, not an instruction to destroy OSS files. Section 1 transfer.

Section 2 ordered the State interim service abolished at close of business December 31, 1945, while permitting State to transfer functions to its own agencies or curtail them meanwhile. The interim office was deliberately short-lived. It cannot be described as the CIA’s direct 1945 creation. Section 2.

Section 3 transferred all other OSS functions, personnel and records to the War Department and terminated the OSS and its director’s office. The War Secretary could discontinue transferred activities when compatible with the national interest. This is more precise than saying every wartime special operation had to continue indefinitely. Section 3.

Sections 4–6 gave the Budget Bureau implementation duties, amended conflicting prior orders and made the main changes effective October 1. Signing, effective agency termination and the State interim service’s separate December endpoint are three different calendar markers in the text. Sections 4–6.

What happened in practice

NARA describes a Strategic Services Unit within War following the OSS transfer and custody of many operational records. This is later evidence of how the residual functions were administered, rather than a clause saying the OSS itself survived. Researchers can trace agency responsibilities through records across the handoff. NARA OSS guide.

NARA records that the CIA was established under the National Security Act of 1947 and that OSS operational records eventually moved into CIA custody. Custody of historic files is not proof the CIA legally existed on October 1, 1945. The 1947 date and intervening units need to be kept visible. NARA CIA history; OSS timeline.

The NARA OSS timeline distinguishes the September 20 presidential signing, the October 1 effective termination and the 1947 statutory CIA establishment. This corroborates the staged chronology in EO 9621 while identifying a later legal source for the permanent postwar intelligence agency. NARA chronology.

The order explicitly excluded Germany and Austria work from the State analytical transfer. That limits what can be concluded from a general archival category such as “research and analysis.” For a particular office file, the location and transfer route must be checked rather than assumed from its branch name. Order section 1.

The June 1942 military order had created the OSS from remaining components of an earlier coordinator of information. NARA describes this earlier formation in its CIA administrative history. The 1945 termination therefore closed a wartime entity whose research and operational branches already had separate functions. The predecessor chain matters when distinguishing analysis records from covert operational files. NARA intelligence history.

Truman allowed the War Secretary to discontinue transferred OSS activities when compatible with the national interest, while the State Secretary could transfer or curtail functions of the interim research service. These are different discretionary authorities over different packages of work. A claim that all OSS programs either continued or stopped on October 1 would ignore the text’s transition powers. EO 9621 sections 2–3.

The State interim service ended by order at the close of December 31, 1945, but its Secretary could transfer individual functions within State before then. That means abolition of this temporary unit was not automatically destruction of every analytical product or record. NARA’s later custody history documents further movement of records as postwar intelligence institutions developed. Truman order; NARA OSS records.

Reaction and legacy

OSS was abolished in October 1945. Analytical and presentation work went temporarily to State; other work and records went to War. The CIA followed later via Congress, not as a direct clause of EO 9621. These relationships are central to an accurate current-status description. Original; NARA CIA history.

The personnel and record transfers preserved some expertise and information across reorganization, but continuity of staff does not mean continuation of an old institution’s legal charter. The December abolition of State’s interim unit reinforces how transitional this particular 1945 plan was. Sections 1–3.

This order explains a historical transition rather than providing present authority for intelligence collection. Modern agency powers turn on later statutes and orders. The official archival chain is enough to describe the 1945 disposition without retroactively attaching 1947 legal effects to Truman’s wartime wind-down. EO 9621 text; NARA agency record.

Two transfers in one termination order

Truman’s EO 9621 ended the Office of Strategic Services after World War II, but did not simply close its files or stop every activity. It divided functions: Research and Analysis and Presentation generally went to a new Interim Research and Intelligence Service in State, while other functions, personnel and records went to War. The text expressly excepted work performed in Germany and Austria from the State transfer. A shorthand that “OSS became CIA” misses both the immediate destinations and the later legislation. Signed order; NARA OSS history.

The order was signed September 20 and, except for specific provisions, took effect at the opening of business October 1, 1945. The interim State service was itself scheduled to end at the close of December 31, with the Secretary able to transfer functions inside the department beforehand. These dates describe a managed transition, not two years of an unchanged OSS. A document’s creation date and the office that later held it can differ. EO 9621 sections 1–6.

Research and analysis at State

The State transfer included branch functions, related personnel, property, records and funds as determined through the budget process. The Secretary of State received the corresponding supervisory functions. An intelligence analysis file could therefore move into State even though the OSS name disappeared. The temporary service was a bridge, and the order permitted State to place functions in departmental agencies before the bridge itself closed. EO 9621 sections 1–2; NARA archival history.

The Germany and Austria exception is a meaningful boundary. The text excluded functions performed there from the specified State transfer, so a researcher cannot classify every Research and Analysis document solely by branch title. Location and function both matter. The archival history and a file’s custody can clarify where a particular operation went in October 1945. Primary order; OSS record guide.

Remaining operations and records at War

Functions not covered by the State transfer, with their personnel, records, property and funds, went to the War Department. The Secretary of War could discontinue activities when compatible with the national interest and wind up their affairs. The order therefore combined transfer with authority to close individual activities. NARA’s OSS records and the Strategic Services Unit history help trace that residual path. EO 9621 section 3; NARA OSS records.

A surviving clandestine file under a later War custodian is not evidence that OSS remained an independent agency. Records can be preserved while their originating office has ended. Conversely, an operational function can continue under a new title. The order explicitly handled both possibilities, and the archive’s record group lets researchers follow originals without conflating records custody with current legal authority. NARA RG 226; EO 9621.

The later intelligence system

The CIA’s later statutory creation is part of the broader postwar intelligence history, not a clause in EO 9621. NARA maintains separate records for OSS and the Central Intelligence Agency. Their institutional connection is real, but the immediate 1945 split through State and War should not be erased in a straight line from OSS to CIA. NARA OSS timeline; CIA record group.

A question about one OSS officer, analysis or operation may require files in several successor series. The order’s transfer rules give a starting map, not a guarantee that every document was moved neatly on the effective date. Later declassification and archival processing also affect what can now be consulted. A present-day intelligence policy cannot be inferred from the 1945 disposition of wartime functions. OSS records; EO 9621.

What termination means here

The order abolished the OSS and the director’s office while identifying destinations for personnel, money and records. That is a more exact meaning of “termination” than imagining an instant disappearance of expertise. The Interim Research and Intelligence Service had a specified sunset, and the War Department held the remainder subject to winding down. These clauses show a deliberate administrative transition at the end of war. EO 9621.

The legal significance is the allocation of a wartime intelligence organization’s functions at a defined moment. The later architecture of intelligence required other acts and decisions. Readers should use the 1945 text for the transition, NARA’s OSS files for implementation and later law for subsequent agencies. That source sequence is more reliable than retrospective descriptions that compress several institutions into one. NARA OSS timeline; original order.

A map of files after the OSS closed

An OSS analytical report could move to State’s interim service, while operational records moved to War. The budget director determined how related personnel and funds were assigned where categories overlapped. These instructions are the administrative basis for a split archive. A researcher who searches only the modern CIA may miss a 1945 State or War custody trail. EO 9621 sections 1–4; NARA OSS records.

The State service had a sunset at the end of 1945. The Secretary could redistribute functions inside State before then, making “interim” a real operational limit rather than a decorative name. The order did not specify the future CIA, which emerged under later authority. EO 9621 section 2; NARA CIA history.

Military personnel could continue on a transferred assignment only within applicable law and agreement among the relevant secretaries. The text did not declare all OSS personnel automatically hired by State or War on identical terms. Employment histories require individual records. EO 9621 sections 1 and 3.

The Germany and Austria exception reflected the particular postwar operating situation. It is explicitly in section 1 and should be preserved in any summary of what went to State. Without it, a researcher could look for all analytical activity under the wrong successor. Signed order.

NARA identifies a Strategic Services Unit under War after the transfer. That confirms a successor for some functions while the OSS legal entity was abolished. It is a good example of the difference between institutional termination and immediate discontinuation of every operation. NARA OSS timeline; RG 226.

OSS records can document a wartime operation, but the very existence of a file does not establish that its plan was executed. Intelligence reporting can contain claims, assessments and unverified leads. The order identifies where files moved; evaluating their content requires source criticism and corroboration. NARA OSS records.

The postwar reorganization occurred amid broader questions about coordinating intelligence. EO 9621 answered the immediate question of where OSS assets and functions went on October 1. Later intelligence structures were separate decisions. A history that jumps straight to the CIA loses this consequential transitional interval. Original order; NARA CIA administrative history.

The order’s present effect is historical: the named OSS and interim service are gone. Its clauses remain vital to provenance, allowing a reader to understand why a report or officer appears in another department’s files. That is a specific archival use of a terminated order, not a claim that it governs today’s intelligence agencies. EO 9621; NARA RG 226.

The interim service was deliberately short-lived

State received Research and Analysis and Presentation functions for an interim period, with authority to reassign or curtail them before December 31. That is a specific legal design: analytical capacity could continue while permanent arrangements were considered. It was not an order making the new State service a standing intelligence agency. EO 9621 section 2.

The budget director’s role in determining related personnel, property and funds is another important operational detail. Branch names were not enough to decide every mixed resource; the order supplied a mechanism for allocating them. A researcher should therefore treat an eventual record location as the product of implementation, not merely the order’s broad category. EO 9621 sections 1 and 4.

NARA’s OSS timeline puts the Strategic Services Unit under War after October 1945 and traces later transitions. That successor was a custodian of certain activities and files, not a legal continuation of the OSS directorate. The difference helps explain why a postwar file may have an OSS origin but bear another office’s stamp. NARA OSS timeline; RG 226.

The CIA came later under congressional action. Calling EO 9621 the order that “created the CIA” would be incorrect. It provides part of the predecessor history, including a State analytical route and War residual route; subsequent national-security legislation supplied the later agency. NARA CIA history; EO 9621.

The specified October 1 effective date should be used when attributing an action. A document signed on September 25 can still belong to OSS before the transfer, while an October document may originate with a successor. The archive’s catalog name may reflect later custody, so contemporaneous letterhead and dates deserve attention. EO 9621 section 6.

The guide’s current-status statement is thus narrow and firm: OSS ended, but its work and papers were distributed. Understanding that split requires the actual clauses, not a one-line successor chart. The order remains a key provenance source for postwar intelligence archives. Primary text; NARA OSS records.

Common questions

Did EO 9621 create the CIA?

No. Congress established the CIA in 1947; the order transferred OSS work to State and War in 1945. NARA.

When did OSS end?

Truman signed on September 20; termination became effective October 1, 1945. EO 9621 text.

Where did the research branches go?

Most went to a temporary State service, with an express Germany and Austria exception. Section 1.

What happened later

The OSS ended on October 1, 1945. An interim Strategic Services Unit and subsequent intelligence reorganizations followed; Congress established the CIA under the National Security Act of 1947.
