The Latvian Communist Party Central Committee (LCP CC), its administrative apparatus and its Bureau, were the highest political and administrative institutions in Soviet Latvia. One of its main functions was the ideological control of society, and the monitoring of any activities considered to be anti-communist or anti-Soviet. Its documents contain an extensive amount of information about direct and hidden resistance to the Soviet regime, about the mood and activities of the intelligentsia, especially writers, artists, etc, members of the creative intelligentsia, and about youth activities, etc. These documents also reflect relations between Moscow and Riga on ideological matters, and hidden and open cultural resistance, especially from the mid-1950s to the end of the 1960s, when Soviet Latvian ideologues tried to adapt Stalinist cultural policies to the new realities of the outside world in connection with the Hungarian Uprising in 1956, the Prague Spring and its suppression in 1968, the  influence of the Western youth movement, etc. The archival documents of the LCP CC contain a vast array of documents of very different kinds, such as the minutes of Party congresses and CC plenary meetings, the minutes of CC Bureau meetings and special meetings on ideological matters, information about the mood, and developments in the cultural sphere, etc.
