Slav • 3rd wife and Duchess of Poland by marriage to Duke Boleslaw I of Poland; Princess of Lusatia as the daughter of Prince Dobromir of the Western Slavs, Lusatia and Milsko and Emnilda of Arneburg, daughter of Bruno, Count of Arneburg

Boleslaw I's marriage to Dobromir's daughter, Emnilda, in 987 ensured peace with this neighbor, now Boleslaw's father-in-law, and the opportunity to defend one another against any enemy.

According to Bishop Thietmar of Germany, Emnilda played an important role at the court. According to the bishop, "the unstable mind of her husband was always guided by Emnilda and she did not cease in her efforts to atone for the sins of both of them through great generosity in alms and suffering."

Gallus Anonymous, also, wrote about Emnilda's important role. Although he did not know Emnilda's name; however, he fixed the memory of the wise and prudent spouse of the ruler, who was able to exert a strong influence on him or even manipulate the powerful prince.

Emnilda managed to prevent the consequences of her husband's impulsiveness.

Bolesław, when angered, would issue many rash and ill-advised death sentences, often against people loyal to him.

Emnilda postponed many executions and as soon as an opportunity arose, she would ask Bolesław for mercy.

Most often, she obtained it.

The efforts of the princess were vividly outlined in Gallus Anonymous:

 "...more than once, Boleslaw I's wife, the queen, had snatched many of those sentenced to death for a crime from the hands of the executioner, saved them from imminent danger of death, prison and, under guard, kept them mercifully alive, sometimes without the king's knowledge, sometimes with his tacit consent."

She was a Slavic princess and by marriage Duchess of Poland. She was a daughter of certain Dobromir, most likely a Slavic ruler of Lusatia and Milsko, who was named venerable (probably meaning "prince") by Thietmar of Merseburg.
