A report on Přemyslid dynasty and Duchy of Bohemia

Vratislaus (or Wratislaus) I (Vratislav I.; c. 888 – 13 February 921), a member of the Přemyslid dynasty, was Duke of Bohemia from 915 until his death.

Upon the death of his elder brother Spytihněv in 915, Vratislaus became duke at a time when the Bohemian lands around Prague Castle had already distanced themselves from the political and cultural sphere of Great Moravia and fallen under the influence of East Francia, especially during the rule of Duke Arnulf of Bavaria.

Boleslaus I (Boleslav I. Ukrutný) (915 – 972), a member of the Přemyslid dynasty, was ruler (kníže, "duke") of the Duchy of Bohemia from 935 to his death.

Wenceslaus I (Václav ; c. 907 – 28 September 935 or 929), Wenceslas I or Václav the Good was the duke (kníže) of Bohemia from 921 until his death probably either in 935 or 929 (although 935 is favored today).

Wenceslaus was the son of Vratislaus I, Duke of Bohemia from the Přemyslid dynasty.

Pobożny; c. 927/928 – 7 February 999), a member of the Přemyslid dynasty, was Duke of Bohemia from 972 until his death.

Boleslaus II took over the rule of the Duchy of Bohemia as kníže (a title that may be translated either as duke or prince) on his father's death in 972.

Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg monarchy and the Austrian Empire.

A native monarchy arose to the throne, and Bohemia came under the rule of the Přemyslid dynasty, which would rule the Czech lands for the next several hundred years.

875 – 915), a member of the Přemyslid dynasty, was Duke of Bohemia from 894 or 895 until his death.

He was the eldest son of Duke Bořivoj I, the first historically documented Bohemian ruler, and his wife Ludmila.

Bořivoj I (, Borzivogius, c. 852 – c. 889) was the first historically documented Duke of Bohemia and progenitor of the Přemyslid dynasty.

His reign over the Duchy of Bohemia is believed to have started about the year 870, but in this era Bohemia was subordinated to Great Moravia.

The kingdom was established by the Přemyslid dynasty in the 12th century from the Duchy of Bohemia, later ruled by the House of Luxembourg, the Jagiellonian dynasty, and from 1526 the House of Habsburg and its successor, the House of Habsburg-Lorraine.

Jaromír (died 4 November 1038 ), a member of the Přemyslid dynasty, was Duke of Bohemia in 1003, from 1004 to 1012, and again from 1034 to 1035.

Vladivoj also secured the support of King Henry II of Germany when he received the Duchy of Bohemia as a royal fief.

The city is believed to be named after Duke Vratislav I of Bohemia from the Czech Přemyslid dynasty, who ruled the region between 915 and 921.

During Wrocław's early history, control over it changed hands between the Duchy of Bohemia (until 992, then 1038–1054), the Duchy of Poland and the Kingdom of Poland (992–1038 and 1054–1202).
