Klaus Henrikinpoika, lord of Joensuu and Kankainen

Klaus Henrikinpoika, lord of Joensuu and Kankainen (c. 1445 – 1520) was in his time one of the most influential magnates in Finland (then a part of Sweden). As keystone of his career, he received the justiciarship of Southern Finland which he held from 1487 to 1520. He was the first male member of his agnatic house to rise to great prominence in his country.

The only surviving son of squire Henrikki Ollinpoika, lord of Joensuu, and his wife (Silja) Laavuntytär of Nyynäinen, heiress of Kankainen manor, he was born in about 1445 or a bit earlier. In his lifetime, no surname was used of him and his family. His forefathers were squire-class noblemen in Finland already in the 14th century (confirmation in 1407 from King Eric XIII) and their family crest depicts 'Drinking Horn'. On the other side, his maternal grandfather (sir Klaus 'djekn' Lyderinpoika) had been as long as for almost two decades (1416..1434) the Castellan of Turku, the regional capital of all Western Finland, and became quite wealthy, so the maternal grandfather's children inherited good fortunes each. Klaus' mother brought the big estate of Kankainen in Masku of southwestern Finland to their own family. Klaus was named after his successful maternal grandfather.

From his father Klaus inherited the Joensuu manor in Halikko, southwestern Finland. Later in life, Klaus inherited Kankainen manor from his sister. Klaus' first wife brought some rights to the manor of Haapaniemi in Kisko to the family, and apparently Klaus purchased other heirs out of that inheritance.

All in all, towards the end of is life, lord Klaus was one of biggest and wealthiest landowners in Finland.

Klaus' second wife inherited several farms in her home district, Vehkalahti, which belonged to the Margraviate of Viipuri (Vyborg).

In 1472, squire Klaus became the district judge of Halikko, the district where his ancestral manor of Joensuu is located. In this position he was successor to his father-in-law, the justiciar 'Kristo' Frille. lord Klaus was the justiciar of Southern Finland as long as over three decades: 1487..1520. Up to 1472, also that office had been held by his father-in-law, 'Kristo' Frille. This position was the most important one in all the judiciary of Finland.
