Sarel Cilliers, South African preacher and activist (d.1871)

Charl (Sarel) Arnoldus Cilliers (7 September 1801 – 4 October 1871) was a Voortrekker leader and a preacher. With Andries Pretorius, he led the Boers to a huge victory over the Zulus at the Battle of Blood River in 1838. In particular, Cilliers lead the Voortrekkers in a vow which promised that if God would protect them and deliver the enemy into their hands, they would build a church and commemorate the day of their victory as if it were an annual Sabbath day, which their descendants would also be instructed to honour.

He was a prominent member of the Gereformeerde Kerk (Reformed Church), an offshoot of the Dutch Reformed Church. He is described as being a short, stout man, and was believed to have been very religious. He joined the Great Trek at the age of thirty-five.The town of Kroonstad was, according to folklore, named after a horse belonging to Cilliers, which drowned in a stream (Kroonspruit) where the town is situated.

There is a Sarel Cilliers Museum as well as a statue of him (on the site of the Dutch Reformed Church) in Kroonstad. Numerous streets and roads in Kroonstad and throughout South Africa are named after him.
