In the early 2010s, Zuism, a revival of the Sumerian religion, was founded in Iceland and formally registered in 2013. In late 2015, the Board of Directors of the Zuist Church was hijacked by people who were unrelated to the movement, and under the new leadership Zuism was turned into a medium for a protest against the state church and the Icelandic church tax ("sóknargjald"). Zuism, unlike other religions, promised to share among its adherents the money it receives from the tax, so that in a few weeks thousands of people joined the church. After a legal struggle, the original directors were reinstated as the leaders of the movement, and by October 2017, after two years of frozen activity, the case was closed allowing the church to dispose of its taxes. This church has kept the principle of funds' redistribution among members, which is called "amargi".
