Triune immersion or trine immersion: the method of baptism practiced by the Church of the Brethren and other Anabaptist churches, in which the baptismal candidate is dunked forward three times, either in an indoor baptistry or outdoor in a lake or river.
Triune kingdom of Croatia (Croatian: "Trojedna Kraljevina Hrvatska") is a historical reference to unified Croatia in a sense that Croat populated medieval kingdoms of Croatia proper, Dalmatia (that had separate identity because of historical development from Byzantinethema, distinct from Slavichinterland) and Slavonia (developed between rivers Sava and Drava and with strong Hungarian influence), became one country. Notion of the "oneness" of Croatia as a single yet triple national state emerged during unification of these lands under AustrianHabsburgdynasty and the name became very popular in late 18th and during 19th century. It is considered archaic today and rearly used.
