Cold War: U.S. President Lyndon B. Johnson meets with Soviet Premier Alexei Kosygin in Glassboro, New Jersey for the three-day Glassboro Summit Conference.

Lyndon Baines Johnson, also known as LBJ, was the 36th president of the United States, serving from 1963 to 1969. He became president after the assassination of John F. Kennedy, under whom he had served as the 37th vice president from 1961 to 1963. A Southern Democrat, Johnson previously represented Texas in Congress for over 23 years, first as a U.S. representative from 1937 to 1949, and then as a U.S. senator from 1949 to 1961.

Alexei Nikolayevich Kosygin was a Soviet statesman during the Cold War. He served as the Chairman of the Council of Ministers from 1964 to 1980 and initially led the Soviet Union as part of a triumvirate in the mid-to-late 1960s.

Glassboro is a borough within Gloucester County, in the U.S. state of New Jersey, within the Philadelphia metropolitan area. As of the 2020 United States census, the borough's population was 23,149, its highest decennial count ever and an increase of 4,570 (+24.6%) from the 18,579 recorded at the 2010 census, which in turn had reflected a decline of 489 (−2.6%) from the 19,068 counted in the 2000 census. Much of the recent and projected growth in Glassboro have been attributed to the growth trajectory of Rowan University, founded in 1923 and formerly known as Glassboro State College. Glassboro and surrounding Gloucester County constitute part of South Jersey.

The Glassboro Summit Conference, usually just called the Glassboro Summit, was the 23–25 June 1967 meeting of the heads of government of the United States and the Soviet Union—President Lyndon B. Johnson and Premier Alexei Kosygin, respectively—for the purpose of discussing Soviet Union–United States relations in Glassboro, New Jersey. During the Arab–Israeli Six-Day War diplomatic contact and cooperation increased, leading some to hope for an improvement in the two countries' relations. Some even hoped for joint cooperation on the Vietnam War. Although Johnson and Kosygin failed to reach agreement on anything important, the generally amicable atmosphere of the summit was referred to as the "Spirit of Glassboro" and is seen to have improved Soviet–US relations.
