Albert the Bear (; c. 1100 – 18 November 1170 ) was the first Margrave of Brandenburg ( as Albert I ) from 1157 to his death and was briefly Duke of Saxony between 1138 and 1142.

Albert was a loyal vassal of his relation, Lothar I, Duke of Saxony, from whom, about 1123, he received the Margraviate of Lusatia, to the east ; after Lothar became King of the Germans, he accompanied him on a disastrous expedition to Bohemia in 1126, when he suffered a short imprisonment.

* Albert I of Käfernburg 1205 – 1232

* Albert II, second monkey in space, died on impact following V2 flight June 14, 1949.

Three years he was occupied in campaigns against the Slavic Wends, who as pagans were considered fair game, and whose subjugation to Christianity was the aim of the Wendish Crusade of 1147 in which Albert took part ; diplomatic measures were more successful, and by an arrangement made with the last of the Wendish princes of Brandenburg, Pribislav of the Hevelli, Albert secured this district when the prince died in 1150.

Albert was married in 1124 to Sophie of Winzenburg ( died 25 March 1160 ) and they had the following children:

# Count Albert of Ballenstedt ( died after 6 December 1172 )

Victoria was in mourning for her grandson, Albert Duke of Clarence, who died January 1892.

Albert died childless and was succeeded by his brother, who became King George.

# Frederick Albert, died young.

Albert Frederick died in the following year.

He never married or had children ; because his brother Henry died before him ( in 1192 ) also without issue, after Otto II's death in 1205 Brandenburg was inherited by his younger half-brother Albert II, son of Otto I and Ada.

Aside from these, thereafter there is no eyewitness to events in Jerusalem until William of Tyre, archbishop of Tyre and chancellor of Jerusalem, who began writing around 1167 and died around 1184, although he includes much information about the First Crusade and the intervening years from the death of Fulcher to his own time, drawn mainly from the writings of Albert of Aix and Fulcher himself.

By the time Albert died 30 years later, the conquest and formal Christianisation of present-day Estonia and northern Latvia was complete.
