Jarich or George van Liauckema (17 December 1558 – 24 August 1642) was a Frisian nobleman and soldier in Spanish service in the Eighty Years' War.

Some time after the Siege of Groningen he returned to Friesland, where in 1618 he again came into possession of the ancestral castle of the Van Liauckema family, the Liauckamastate in Sexbierum.

He started as vaandrig, but in 1582 he was involved as a captain, together with his brother-in-law Tiete van Cammingha, in the Capture of Steenwijk under the command of Jean Baptiste de Tassis.

[2] After De Tassis was killed in the Siege of Bonn in 1588, Van Liauckema succeeded him as governor of Zutphen.

[5][6] In Groningen, Van Liauckema commanded 900 Spanish soldiers stationed in the Schuitenschuiverskwartier east of the city.

This caused much disagreement within the city between the proponents and opponents of peace negotiations with the States Army, the Staatsen.

On 23 July, the Tractaat van Reductie (Treaty of Reduction) was signed and the city passed into the hands of the Staatsen.

Van Liauckema had stipulated that the soldiers would be taken in convoy to Verdugo's army in Twente, in armour, with a flying banner and a beating drum.

[7] They then marched to Oldenzaal but had to continue, across the Rhine, since it had also been agreed that they were not allowed to carry out any military operations north of this river for three months.

[14] Although Van Liauckema remained a Catholic, he seems to have reconciled himself with the Protestants, as he was one of those present at the funeral of Ernest Casimir of Nassau-Dietz in 1633.

[19] When Jel became a widow, she moved permanently to the Liauckamastate with her daughter Sophia Anna van Pipenpoy.

Sophia Anna died childless in 1670, after which the estate came into the hands of her cousin, Alexander Josephus van der Laen.

She married Dierick van der Laen, lord of Schriek and Grootlo and mayor of Mechelen, on 4 August 1616.
