Leo II of Galicia, also known as Lev Yurevich (unknown – 1323) was Prince of Lutsk and Galicia, one of the last two Rurikid kings of Galicia-Volhynia (r. 1308–1323; according to some sources, 1315–23). He was a member of the senior branch of Monomakhovichi.
He was the son of King Yuri I (1252–1308), whom he succeeded on the royal throne of Galicia-Volhynia. After the death of his father, he ruled the kingdom together with his brother Andrey. His mother was Euphemia of Kuyavia. According to most sources, the brothers were co-kings, managing the kindgdom together, but there are sources indicating that Lev II was seated in Halych and Andrew in Vladimir-in-Volhynia (and yet others stating a similar arrangement, but with the seats reversed), which would seem to imply split jurisdiction.
The first common Letter of Lev II and Andrey dates to August 9, 1316, in which they renewed the union with the Prussian Crusaders (the Teutonic Order, also known as the Teutonic Knights), whom they promised to defend from the Tatars and "any hostile invader"; the latter mention apparently referred to the Grand Duchy of Lithuania, as that state at the time threatened not only the unity but also the very existence of both the Knights and the Galician state.
Leo II (or Leon II) may refer to:
Leo II (Latin: Flavius Leo Iunior Augustus, Ancient Greek: Λέων Β', Leōn II; 467 – 17 November 474) was Byzantine Emperor for less than a year in 474. He was the son of Zeno and Ariadne, and maternal grandson of Leo I and Verina. As Leo's closest male relative, he was named successor upon his grandfather's death. After taking his father as colleague, he died of an unknown disease about 10 months into his reign in November, 474. It was widely rumored that he might have been poisoned by his mother Ariadne in order to bring her husband Zeno to the throne. He was indeed succeeded by his father, although his grandmother Verina took advantage of his death to conspire against Zeno.
Leo II (or Leo B) is a dwarf spheroidal galaxy about 690,000 light-years away in the constellation Leo. As of October 2008 it is one of 24 known satellite galaxies of the Milky Way. As of 2007 Leo II is thought to have a core radius of 178 ± 13 pc and a tidal radius of 632 ± 32 pc. It was discovered in 1950 by Robert George Harrington and Albert George Wilson, from the Mount Wilson and Palomar Observatories in California.
In 2007 a team of 15 scientists observed Leo II through the 8.2 meter Subaru optical-infrared telescope in Mauna Kea, Hawaii. Over 2 nights, 90 minutes of exposures were taken and 82,252 stars were detected down to a visible magnitude of 26. They found that Leo II consists largely of metal-poor older stars, a sign that it has survived the galactic cannibalism under which massive galaxies (e.g., the Milky Way) consume smaller galaxies to attain their extensive size.
Observation at ESO estimates Leo II's mass to be (2.7 ± 0.5)×107M⊙.
Halych (Ukrainian: Галич, Halych; Romanian: Halici; Polish: Halicz, Halich; Russian: Галич, Galich, German: Halytsch) is a historic city on the Dniester River in western Ukraine. The town gave its name to the historic province and the Kingdom of Galicia–Volhynia, of which it was the capital until the early 14th century, when the seat of the local princes was moved to Lviv.
In the past, the town belonged to several countries. In 1349, together with Red Ruthenia, it was annexed by Polish King Casimir III the Great. After his death, it was ruled by the Kingdom of Hungary (1370-1387). For the next 400 years, it was part of Poland’s Ruthenian Voivodeship, but following the first partition of Poland (1772) it became part of Austrian Galicia, in which it remained until late 1918. Between November 1918 and May 1919, Halych belonged to short-lived West Ukrainian People's Republic. From May 1919 until September 1939 (see Soviet invasion of Poland), Halicz the seat of a county in Second Polish Republic’s Stanisławów Voivodeship.
