ia, became duke
on his father's death in 1523. He ruled for a time in common with his elder
brother George; and after George's death in 1531 he shared the duchy with
his nephew Philip I., retaining for himself the duchy of Pomerania-Stettin.
The earlier years of his rule were troubled by a quarrel with the margrave
of Brandenburg, who wished to annex Pomerania. In 1529, however, a treaty
was made which freed Pomerania from the supremacy of Brandenburg on
condition that if the ducal family became extinct the duchy should revert
to Brandenburg. Barnim adopted the doctrines of Martin Luther, and joined
the league of Schmalkalden, but took no part in the subsequent war. But as
this attitude left him without supporters he was obliged to submit to the
emperor Charles V., to pay a heavy fine, and to accept the _Interim_,
issued from Augsburg in May 1548. In 1569 Barnim handed over his duchy to
his grand-nephew, John Frederick, and died at Stettin on the 2nd of June
1573.

BARNSLEY (BLACK, or properly BLEAK BARNSLEY), a market town and municipal
borough in the Barnsley parliamentary division of the West Riding of
Yorkshire, England, 15 m. N. of Sheffield. Pop. (1891) 35,427; (1901)
41,086. It is served by the Midland, Great Central, Lancashire & Yorkshire,
Great Northern, and Hull & Barnsley railways. It is in the parish of
Silkstone, which gives name to important collieries. It is situated on
rising ground west of the river Dearne, and, though it loses in attraction
owing to its numerous factories, its neighbourhood has considerable natural
beauty. Among the principal buildings and institutions are several
churches, of which the oldest, the parish church of St Mary, was built in
1821 on an early site; court house, public hall, institute and free
library. Among several educational institutions, the free grammar school
dates from 1665; and a philosophical society was founded in 1828. A
monument was erected in 1905 to prominent members of the Yorkshire Miners'
Association. The park was presented in 1862 by the widow of Joseph Locke,
M.P. The manufacture of iron and steel, and the weaving of linen and other
cloth, are the two principal industries; but there are also bleachfields,
printfields, dyeworks, sawmills, cornmills and malt-houses; and the
manufacture of glass, needles and wire is carried on. There are large
coalfields in the neighbourhood, which, indeed, extend under the town. Coal
and coke are largely exported to London an
