The Imperial Council was the legislature of the Austrian Empire from 1861 until 1918. It was a bicameral body: the upper house was the House of Lords, and the lower house was the House of Deputies. To become law, bills had to be passed by both houses, signed by the government minister responsible, and then granted royal assent by the Emperor. After having been passed, laws were published in the Reichsgesetzblatt. In addition to the Imperial Council, the fifteen individual crown lands of Cisleithania had their own diets.

The Austrian Empire, officially known as the Empire of Austria, was a multinational European great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous monarchy in Europe after the Russian Empire and the United Kingdom. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third-largest empire in Europe after the Russian Empire and the First French Empire.
