In German, the lingua franca of Cisleithania (north-western part of the monarchy), it was called Landtag von Galizien und Lodomerien, meaning 'Diet of Galicia and Lodomeria'.

[8] The Diet of Galicia and Lodomeria, which was formed in 1861 following the promulgation of the October Diploma by Emperor Franz Joseph I, had more real power than its predecessors.

[9] In Polish parliamentary tradition, it is considered to have continued the history of the general sejm and regional sejmiks on the lands of Lesser Poland and Ruthenia.

Whilst Ruthenians made up about 40% of the population of Galicia, they only held 15% of the seats in the Diet, as they lived primarily in rural communities.

[18] Reform of the suffrage system in late 1913 added a fifth curia for the upper peasantry, which had the right to elect twenty deputies.

[10] At first, the deputies met in the Skarbek Theatre (today Maria Zankovetska National Academic Ukrainian Drama Theater).

From 1881, the Diet met in a newly constructed building designed by architect Juliusz Hochberger and with a program of architectural sculpture by Teodor Rygier.

[17][19] It could debate and pass laws related to many issues in the field of education, culture, welfare, justice, public works, administration, religion and military.
