Wie trouwde met Konstantin Tih?

Constantine I Tih (Bulgarian: Константин I Тих, romanized: Konstantin I Tih) was the tsar of Bulgaria from 1257 to 1277, he was offered the throne from Mitso Asen. He led the Bulgarian Empire at a time when the nearby Byzantine Empire disintegrated into rump states. To strengthen his position, he forged an alliance with one of the rump states—Nicaea—by marrying Irene, a daughter of Theodore II of the prominent Laskaris family.

Early in his reign, his army invaded Severin, Hungary which outraged Béla IV; this led Hungarian troops to capture Vidin, an important town of the Bulgarian Empire and also saw the Hungarians besieging the Lower Danube region, leaving northwestern Bulgaria to Rostislav Mikhailovich (Béla's son-in-law), who had claimed Bulgaria in the years prior.

When Michael VIII took over the throne of the Byzantine Empire (which led Konstantin to go to war with them in the 1260s) this saw Bulgaria losing significant territories to its two principal enemies, the Byzantines and Hungary. Later, when Tatars began attacking the Byzantines, Konstantin joined them in a unified attack but this failed to capture Michael VIII.

After Stephen emerged victorious in the Hungarian civil war, he began attacking Bulgaria again and defeated Konstantin's army. He plundered Tarnovo and captured fortresses on the Danube in the mid to late 1260s. Later, Konstantin suffered an injury and was paralysed from the waist down. The paralysed Konstantin failed in preventing the Nogai Horde from plundering Bulgaria. Further worsening his situation, the latter part of his reign saw economic instability and his failed suppressing of a revolt ended his life.

Irene Doukaina Laskarina (Bulgarian: Ирина Ласкарина Асенина, romanized: Irina Doukaina Asenina, Greek: Ειρήνη Δούκαινα Λασκαρίνα, romanized: Eirēnē Doúkaina Laskarina) was empress consort (tsaritsa) of Bulgaria (1258–1268). She was the second wife of Tsar Constantine Tikh of Bulgaria.

She was a daughter of Emperor Theodore II Laskaris of Nicaea, and his wife Elena of Bulgaria, and sister of Nicaean Emperor John IV Laskaris. Her maternal grandparents were Tsar Ivan Asen II and Anna Maria of Hungary.

In 1257, Irene married Bulgarian nobleman Constantine Tikh as his second wife. Her husband was a pretender to the Bulgarian crown. Constantine was proud to be married to a granddaughter of Tsar Ivan Asen II, and he adopted the Bulgarian dynastic name Asen to enhance his claim to the crown. In the next year Constantine was elected Tsar of Bulgaria by a boyar council in Tarnovo and Irene become his consort.

In 1261 Irene's young brother, Emperor John IV Laskaris, was deposed and blinded by Nicaean regent Michael VIII Palaiologos, who had just regained Constantinople from the Latin Empire, re-establishing the Byzantine Empire. Tsaritsa Irene was a bitter enemy of the usurper. She became a leader of the anti-Byzantine party in the Bulgarian court.

Irene died in 1268. She had no children.
