[citation needed] The noble family Loewenstein-Wertheim goes back to the Wittelsbach Friedrich I., the Victorious, Elector of the Palatinate (1425–1476) and his son Ludwig.

During the time of the Weimar Republic, Löwenstein joined various organizations that were active in the environment of the right-wing extremist Hugenberg Press.

Mussolini's Italy appeared to Löwenstein in 1931 as the better alternative, also with a view to an official leadership role of the aristocracy that was once again possible in a civil society.

As President of the Central Committee, he showed unconditional commitment to the Church and the Pope and gained respect in wide circles of post-war West German society during the Adenauer era.

Together with the President of the Evangelical Church Day, Reinhold von Thadden-Trieglaff, he organized ecumenical encounters between Catholics and Protestants.

When Löwenstein's behavior during National Socialism came into public discussion in 1967 after his appointment as a member of the World Lay Council, he resigned as President of the Central Committee in the same year.
