940/45 – 977) was a Bohemian princess of the Přemyslid dynasty and by marriage Duchess of the Polans.
She was the daughter of
Boleslaus I the Cruel, Duke of Bohemia, whose wife may have been the mysterious Biagota.
According to earlier sources, Doubravka urged her husband
Mieszko I of Poland to accept baptism in 966, the year after their marriage.

Gunther, Margrave of Merseburg

In 962, he was already regarded as a margrave in the newly created Diocese of Magdeburg, alongside Count Wigger of Bilstein and Wigbert.
He was appointed to the newly created Merseburger march by Emperor Otto
I following the death of Margrave Gero the Great in 965, after which the "Marca Geronis" was split in several smaller parts.
The establishment of the march was followed by the Merseburg diocese under Bishop Boso in 968.
Gunther supported Duke Henry II
the Quarrelsome of Bavaria in his revolt against Emperor Otto II and was therefore deposed as margrave and banished in 976, while his march fell to Thietmar of Meissen.
Gunther nevertheless became reconciled with Otto II and after Thietmar's death in 979 was reinstalled as margrave.
He joined Otto's campaign in Calabria in 982 and died there in the Battle of Stilo against the Saracens.
He was succeeded by Rikdag, who then united the marches of Meissen, Merseburg and Zeitz under his rule.
According to chronicler Thietmar of Merseburg, Gunther may have been married to Dobrawa, daughter of Duke Boleslaus the Cruel of Bohemia and consort of Duke Mieszko I of Poland from 965.
He left three sons:
Eckard I, who succeededed Rikdag as Margrave of Meissen in 985; Gunzelin of Kuckenburg, who followed his brother in 1002, and Bruno, who defended Meissen against the troops of duke Bolesław
I Chrobry of Poland in 1009.
