Albert II was the youngest son of Otto I and his second wife Ada of Holland. His father Otto I promoted and directed the foundation of German settlement in the area, which had been Slavic until the 10th century.
Count of ArneburgEdit
When Henry of Gardeleggen died in 1192, he left his domains to Albert II. But that caused a conflict between himself and his brother. He was temporarily imprisoned in 1194 by Otto.
Margrave of BrandenburgEdit
Albert II inherited the Margraviate in 1205, after the death of his eldest brother Otto II.
In the dispute about the imperial crown between the Houses of Hohenstaufen and Guelph in the early 13th century, Albert initially supported the Hohenstaufen King Philip of Swabia, like Otto before him. After Philip's assassination in 1208, however, he changed sides, because Emperor Otto IV had assisted him in securing the Margraviate against the Danes, and had confirmed Ascanian ownership of Brandenburg in a deed in 1212.
Death and successionEdit
Albert II died in 1220. At the time, his two sons were still minors. Initially, archbishop Albert I of Magdeburg acted as regent. In 1221, however, Albert's widow, Countess Matilda, took up the regency. After her death in 1225, the brothers were declared legal adults and began ruling the Margraviate jointly.
Stephan Warnatsch describes Otto I's children as follows:
[They] continued the territorialisation drive that had been initiated [by their father] and, from the end of the 12th Century, as the influx of settlers grew stronger, and, consequently, more people were available to develop the territory, started to expand into the areas of Ruppin, and in particular, Barnim and Teltow. Moreover, the Oder region and the southern Uckermark were also targets of the Ascanian expansion. In all these areas, the Ascanians ran into opposition from competing local princes.
Marriage and issueEdit
In 1205, Albert married Matilda of Groitzsch (1185–1225), daughter of the Count Conrad II of Lusatia, a member of the House of Wettin, and wife Elizabeth, from the Polish Piast dynasty. They had four children:
- John I (born: c. 1213; died: 4 April 1266)
- Otto III "the Pious" (born: 1215; died: 9 October 1267)
- Matilda (died: 10 June 1261), married in 1228 Duke Otto I "the Child" of Brunswick-Lüneburg (1204–1252), a member of the House of Guelph
- Elizabeth (born: 1207; died: 19 November 1231), married in 1228 Landgrave Henry Raspe of Thuringia (1201–1247)
