In the summer of 1945 Scharnagl was one of the leaders in the preparations for the founding of the Christian Social Union in Bavaria (CSU). Through his organization, a meeting of twelve persons was held on August 14, which discussed the possibility of establishing a conservative-bourgeois party as a counterweight to the "socialist camp". A committee to prepare the party's founding was used and adopted at a further meeting on September 12, which is considered the actual founding meeting of the CSU, under the name of the
Bavarian Christian Social Union. The statewide official founding as Christian Social Union, was on October 13 in
Würzburg. On June 6, 1946 Karl Scharnagl was officially voted in as mayor in his office, but two years later he was defeated by
Thomas Wimmer (SPD). He served one year as the second mayor, and then went into retirement in 1949. On May 22, 1945, Scharnagl received the allowance from the
American military government the authority to re-establish the organization of the
Red Cross for Bavaria. He called upon
Adalbert Prince of Bavaria to become its president. On 1 June 1946 he was elected honorary president of the Bavarian Red Cross (BRK) and on 12 April 1947 he was elected president. 1948 Scharnagl co-founded the
Society for Christian-Jewish Cooperation. From 1947 to 1949 he was a member of the
Bavarian Senate. He was a member of the Catholic
fraternity K.S.St.V. Alemannia Munich,
Kartellverband. On April 6, 1963, Karl Scharnagl died. He was buried in the
