1163 –
19 March 1238), of the Silesian line of the

Biography
Henry was born in
Głogów,
Silesia.
In 1186, Henry and 12 year old
Hedwig of Andechs () were married at ''Burg
Andechs''. Hedwig was canonized in 1267. His son and successor, Duke
Henry II the Pious, would be killed in 1241 battling the
Mongols at ''Liegnitz'' (
Legnica).
In 1201 Henry succeeded his father, Duke
Bolesław I the Tall, who was subject of the
Holy Roman Empire as he had received the Silesian ducal position following an 1163 intervention by
Holy Roman Emperor Frederick I Barbarossa in a succession dispute. In 1205 he agreed to exchange the territories of
Lubusz with
Władysław III Spindleshanks of
Greater Poland, receiving
Kalisz. When in 1210
Conrad of Lusatia conquered Lubusz, Henry intervened and reconquered the region.

The black crownless eagle of the Silesian Piasts.
In 1217, through the mediation of the bishops of Poznań e Lubusz, he signed with Władysław Spindleshanks a treaty, which was approved by a
Papal Bull on
May 9 1218. By it, Henry gave back Lubusz and renounced any claim over ''Calisia'' Kalisz and other
Ladislas Odonic's lands. In exchange, Henry was named heir to the childless Duke of Greater Poland.
In 1222-1223 he took part in the Crusades against the pagan
Old Prussians. In 1225 he attempted to conquer
Cracow, but had to raise the siege after a few days.
On
November 23 1227, during an assembly of Piast dukes at
GÄ…sawa, he was seriously wounded in an ambush by Ladislas Odonic and
Świętopełk II of Pomerania, while
Leszek I the White was killed in the same. This act started a feud for the conquest of the Polish throne, in which Henry supported
Władysław III, who ultimately gained it. When in the summer 1228
Conrad I of Masovia attacked
Lesser Poland, he was pushed back by Henry's son,
Henry II the Pious; Conrad was however more successful the following year, being able also to take Henry I as prisoner. He was released under the promise to renounce Cracow. Later the Pope freed him of this promise obtained under constriction.
In 1230 he was to reunite the whole Silesia under his reign through the acquisition of the Duchy of
Opole. Henry became Duke of Cracow in 1232, and assumed control over the Duchy of
Sandomierz as the tutor of
Bolesław V the Chaste.
In the Spring of 1231 Henry launched an offensive against Ladislas Odonic, who was claiming Greater Poland. The invasion was a failure. He was more successful three years later, when he managed to conquer Greater Poland up to the
Warta River. In 1234 his son Henry II the Pious received the throne of Greater Poland.
During his reign, Henry improved the economy and infastructure of his lands by supporting the immigration of German settlers (
Ostsiedlung), mainly from the home of his wife,
Franconia and
Bavaria.
Henry died at
Krosno Odrzańskie in 1238 and was buried in the
Cistercian church of Trebnitz (
Trzebnica) which he had founded in 1202 on the request of his wife.
