This series reflects primarily the activities of John D. Rockefeller, Jr., but significant documentation on the political and civic concerns of each of his sons is also present. In addition to extensive files on family support of the Republican Party on the national, state, and local level, separate folders exist on specific candidates, such as President Dwight D. Eisenhower, New York City Mayor Fiorello La Guardia, and New York Governor Thomas Dewey. There are substantial files on family support for Nelson Rockefeller during his first gubernatorial campaign and immediately afterward. However, very little material exists in this series on his presidential effort in 1960.

The files on Rockefeller involvement with "good" government groups is, from an historical point of view, at least as significant as the political files. Organizations such as the Bureau of Municipal Research and the National Civic Federation provided the personnel and the theoretical underpinnings for the revolution in government which occurred during the course of the twentieth century. Rockefeller involvement with these groups through the end of the 1950s is well documented in this series.

Civic involvement of a different nature is also to be found in this series. The family's concern for an involvement with the problems and organizations of Tarrytown, Westchester County, and New York City constitute a large portion of this series. These are primarily relationships with local fire departments, grand juries, transportation departments, and police.

Finally, Nelson Rockefeller's service in the administration of President Franklin D. Roosevelt and President Dwight D. Eisenhower, and John D. Rockefeller 3rd's participation in the Japanese Peace Treaty negotiations in 1951 are included in this series.
