Louis V, called the Brandenburger, a member of the House of Wittelsbach, ruled as Margrave of Brandenburg from 1323 to 1351 and as Duke of Bavaria from 1347 until his death. From 1342 he also was co-ruling Count of Tyrol by his marriage with the Meinhardiner countess Margaret.

The (Princely) County of Tyrol was an estate of the Holy Roman Empire established about 1140. After 1253, it was ruled by the House of Gorizia and from 1363 by the House of Habsburg. In 1804, the County of Tyrol, unified with the secularised prince-bishoprics of Trent and Brixen, became a crown land of the Austrian Empire. From 1867, it was a Cisleithanian crown land of Austria-Hungary.
