. They were both powerful leaders who had originally been bitter enemies, but with the approaching threat of Lutheranism, they found common cause as allies against religious reform. Denmark had been embroiled in civil war during the
dissolution of the Kalmar Union, and the two Icelandic bishops had held both secular and ecclesiastical power in the country for many years.

Danish efforts at Reform

Gissur Einarsson (c. 1512 – 24 March 1548; Modern Icelandic: ) was a bishop in Skálholt from 1540 to his death, and the first Lutheran bishop in Iceland.
Gissur was the son of Einar Sigvaldason on Hraun í Landbroti and of Gunnhildur Jón ...
, who was secretly in favour of religious reformation. In 1539, bishop Ögmundur, who was almost blind now, made him his successor, and Gissur was consecrated bishop while Ögmundur still lived. The old bishop came to regret his decision when his protégé's Lutheran views surfaced. However, he was at this point very old and infirm, and could do little to stem Gissur's influence, although he nominally shared the see with him.
Bishop Ögmundur seized

In the spring of 1541, Danish soldiers under the command of
Christoffer Huitfeldt landed in Iceland, arrested Ögmundur and took him to Denmark. He died in Danish custody in 1542. Gissur was now free to introduce Lutheran religious reforms unopposed, but did not make the progress he had hoped for. Not all Icelanders were happy with the reforms, and the see of

. In the ensuing years, Iceland remained divided into Protestants and Catholics, but Gissur and Jón Arason kept the peace.
Jón Arason fights back
When Protestant bishop Gissur Einarsson died, Jón Arason made his move. He was the last remaining Catholic bishop in the
Nordic countries, and he intended to reintroduce Catholicism. Jón rode to Skálholt to occupy it and oversee the election of a new bishop. However, the people at Skálholt were prepared for the attack, and after a five-day siege, Jón was forced to give up and ride away.
Jón brought about the election of abbot
Sigvarður Halldórsson in
Þykkvabær as bishop of Skálholt, and sent him to Denmark to be consecrated. This was refused. Sigvarður died abroad in 1550, after adopting Lutheranism. Instead
Marteinn Einarsson
’Marteinn Einarsson (died 7 October 1576) was bishop of Skálholt from 1548 to 1556. He was the second Lutheran bishop and was directly involved in the Icelandic Reformation.

Marteinn returned to Iceland in 1549. Jón then sent his sons, Ari and Björn, to arrest him. They brought him to Hólar, where he remained in custody throughout the following year. In the spring of 1550, Jón travelled to Skálholt, where he exhumed and desecrated the corpse of bishop Gissur, denouncing him as a heretic.

, brother of bishop Marteinn, and
Daði Guðmundsson of
Snóksdalur, the bishop's brother-in-law, who was loyal to the king, and had been entrusted with capturing Jón Arason.
That autumn, Jón and his sons rode west to Dalir with the aim of getting Daði under their power, either through coercion or compromise. They stopped in Sauðafell for a few days, during which Daði gathered many men and overpowered them in a brief struggle known as the
Battle of Sauðafell. They were taken to Skálholt, but fears that they might be rescued by Catholic Icelanders resulted in a speedy beheading for all three on November 7, 1550.

Catholicism outlawed and Danish rule strengthened
With Lutheranism securely in place, Catholicism was outlawed, and all Catholic church property was seized by Iceland's secular rulers. The lands belonging to the Icelandic churches fell into the hands of the
