Scottish Clans
The Gaelic word "clan" means "children",
but it is also used to describe a large group of
families, all related to the same ancestors.
The Scottish clans began 800-1,000 years
ago in the Highlands of northern Scotland.
Each clan might have included several
thousand people, and was ruled by a chief. All
members of a clan were expected to be loyal
to the chief and to each other. Fighting
between clans was common, and powerful
clans such as the MacDonalds or the
Campbells had wide areas of clan territory.
All members of a clan had the same
surname, and all wore the same tartan. This is
a type of woollen cloth with a pattern of
coloured checks, and each clan had its own
design. In early Scotland, only Highlanders
wore kilts
Lowlanders, as Scots from the
south are called, saw them as barbaric. In
those days the kilt was just a long piece of thick
tartan cloth wrapped around the body and
held in place with a belt.
Nowadays, kilts are part of the national
dress of Scotland, and are worn with pride by
Highlanders and Lowlanders alike.
