The International Paneuropean Union, also referred to as the Paneuropean Movement and the Pan-Europa Movement, is the oldest European unification movement. It began with the publishing of Count Richard von Coudenhove-Kalergi's manifesto Paneuropa (1923), which presented the idea of a unified European State. Coudenhove-Kalergi, a member of the Bohemian Coudenhove-Kalergi family and the son of an Austro-Hungarian diplomat and a Japanese mother, was the organisation's central figure and President until his death in 1972.

Richard Nikolaus Eijiro, Count of Coudenhove-Kalergi[1] (November 16, 1894 – July 27, 1972) was an Austrian-Japanese politician, philosopher, and Count of Coudenhove-Kalergi. The pioneer of European integration, he served as the founding president of the Paneuropean Union for 49 years, which would be the preliminary ideological foundation of the European Union.[2][3] His parents were Heinrich von Coudenhove-Kalergi, an Austro-Hungarian diplomat, and Mitsuko Aoyama, the daughter of an oil merchant, antiques-dealer, and major landowner in Tokyo.[4] His childhood name in Japan was Aoyama Eijiro. He became a Czechoslovak citizen in 1919 and then took French nationality from 1939 until his death.
