In the decades before it was settled by white immigrants, York Township and the surrounding area were the domain of the Potawatomi Indians.

The first recorded white settler in York Township was Fayette Barron, who built a homestead at what would become Metz in 1836. The following year saw the arrival of the Powers families, who settled in the northwest sections of the township. Two Powers brothers had scouted the area the year before, and now brought six families on a long journey from New York state.

In 1879, the Powers families and neighbors built what is now known as the Powers Church. The land for a nondenominational church (hence its other name "Free Church") had been donated in 1839 by Clark Powers, head of one of the original Powers families. The last regular services were held at the church in the 1920s. The church was restored in 1976 and added to the National Register of Historic Places in 1983.

The unincorporated village of Metz enjoyed its heyday during the late 19th and early 20th centuries. At one point or another it boasted a sawmill, a hotel, physicians, an undertaker, and several of the more typical retail shops. In 1919, the York township schools were consolidated with those of Richland Township into the Metz school. This school, with students from kindergarten through high school, operated for 40 years, until it was closed in 1959, a victim of declining enrollment.
