The Kingdom of Bavaria (German: "Königreich Bayern" ) was a German state that succeeded the former Electorate of Bavaria in 1805 and continued to exist until 1918.
 The Bavarian Elector Maximilian IV Joseph of the House of Wittelsbach became the first King of Bavaria in 1805 as Maximilian I Joseph.
 The crown would go on being held by the Wittelsbachs until the kingdom came to an end in 1918.
 Most of Bavaria's present-day borders were established after 1814 with the Treaty of Paris, in which Bavaria ceded Tyrol and Vorarlberg to the Austrian Empire while receiving Aschaffenburg and Würzburg.
 With the unification of Germany into the German Empire in 1871, the kingdom became a federal state of the new Empire and was second in size, power, and wealth only to the leading state, the Kingdom of Prussia.
 In 1918 Bavaria became a republic, and the kingdom was thus succeeded by the current Free State of Bavaria.

Dáil Éireann served as the directly elected lower house of the Oireachtas of the Irish Free State from 1922 to 1937.
 The Free State constitution described the role of the house as that of a "Chamber of Deputies".
 Until 1936 the Free State Oireachtas also included an upper house known as the Seanad.
 Like its modern successor, the Free State Dáil was, in any case, the dominant component of the legislature; it effectively had authority to enact almost any law it chose, and to appoint and dismiss the President of the Executive Council (prime minister).
 The Free State Dáil ceased to be with the creation of the modern 'Dáil Éireann' under the terms of the 1937 Constitution of Ireland.
 Both the Dáil and Seanad sat in Leinster House.
