In 1909 there were elections to the Silesian Parliament in Opava.

He was a Senator of the Republic of Poland and a member of the Silesian Parliament from 1922 until his death.

The Polish Government had decided to give Silesia considerable autonomy with the Silesian Parliament as a constituency and the Silesian Voivodeship Council as the executive body.

This culminated in a nationalistic call for Polish Catholics and Polish Protestants to work together in selecting and voting for candidates in the forthcoming elections for the Silesian Parliament.

After the annexation of Zaolzie region to Poland in 1938, President Ignacy Mościcki named him a deputy of the Silesian Parliament, where Łukosz was a deputy until the outbreak of World War II.
