too.
The success of the Danish kings Harald and Sven in extending Danish
hegemony in Scandinavia was not welcomed by all, and some men who were
unwilling to submit went into exile as Vikings. Successful Vikings could chal-
lenge Danish power, as Olav Tryggvason did. To meet that threat Sven himself
led raids on England to gather plunder and tribute with which he could reward
his supporters and the warriors on whom his power largely depended. Sven’s
attacks on England culminated in his conquest of the kingdom in 1013.For
most of his reign Sven Forkbeard was the most powerful ruler in Scandinavia.
He had many advantages. He could not only draw on the resources of the
most fertile and densely populated region of Scandinavia, but also controlled
the entrance to the Baltic and could, therefore, profit from the flourishing trade
between the lands round that sea and western Europe. The Danes had long
benefited from this traffic but the extension of the Danish kingdom in the
latter part of the tenth century to span
¨
Oresund enabled Harald and Sven to
control it more effectively than their predecessors. This provoked opposition
and, significantly, the first information about relations between the Danes and
the Svear in the tenth century is the report that Erik, king of the Svear, formed
an alliance against the Danes with Mieszko, the Polish ruler, whose daughter he
married. Adam of Bremen, whose Gesta Hammaburgensis Ecclesiae Pontificum,
written in the 1070s, is the main source of information about Scandinavia at
that time, claimed that Sven was defeated and driven into a prolonged ex-
ile. That was a wild exaggeration. Whatever success the allies had, the tables
were soon turned, and Sven marked his triumph by marrying Erik’s Polish
widow and then rejecting her after she had given birth to two sons, Harald and
Knut, and a daughter, Estrid. By the end of the century Erik’s son Olof had
acknowledged Sven as his overlord, and supported him in battle against Olav
Tr yggvason. Olof’s subordination is reflected in his nickname Skotkonungœr
(Mod. Swedish Sk
¨
otkonung). This was first recorded in the thirteenth century
but it was probably given at an early date and meant, according to Snorri
Sturluson, ‘tributary king’, and was equated by him with ‘jarl’.

After Sven’s death in February 1014 his empire disintegrated. His son Knut,
who had taken part in the English campaign, was elected king by the army,
but when the English refused to accept him Knut was forced to return to
Denmark. He apparently expected to be recognized as king by the Danes, for
he had some coin dies giving him that title made by English craftsmen.

The
Danes had, however, chosen Harald as their king. In 1015 Knut returned to
