Bennett County is a place in South Dakota, a state in the United States. In 2020, about 3,381 people lived there. The main town, where the county government is, is called Martin.
Long ago, this area was part of the Pine Ridge Indian Reservation. Even today, much of the land is still held in trust for the Native American tribes. To the east is the Rosebud Indian Reservation, home to the Sicangu Oyate, also known as the Rosebud Sioux Tribe. They are part of the Lakota people.
Bennett County is home to a special spot called the "North American continental pole of inaccessibility". This means it's the farthest place from any ocean in North America! It's about 1,650 kilometers (1,025 miles) from the nearest coast. This spot is located between Allen and Kyle.
For a long time, people in Bennett County mainly raised cattle (ranching) and grew crops without much rain (dry land farming). This was because of the weather and soil conditions.

History of Bennett County
This land has been the home of the Oglala Lakota people, also known as the Sioux, for many centuries. It became part of their official territory through a treaty in 1851. The land stayed within their legal boundaries even after other treaties changed their land to the current size of the Pine Ridge Indian Reservation in 1889.
Even though it was a reservation, most of the county was opened for new settlers in 1910. The U.S. Congress allowed the sale of land in Bennett County that was part of the Pine Ridge Indian Reservation. This open settlement ended in 1936, when the land was returned to tribal ownership. Because of these changes, the county's land is a mix of tribal trust lands and private lands.
Bennett County was officially created in 1909. Its land was taken from Fall River County. On April 27, 1912, the county's first leaders were chosen. In November 1912, the people living there chose the town of Martin to be the county seat.
Disputes Over Reservation Status
There have been different ideas about whether Bennett County is still part of the Pine Ridge Reservation. In 1975, a court said it was not part of the reservation. However, the U.S. government did not fully agree with this decision.
Other court cases have said that Bennett County is within the Pine Ridge Indian Reservation. For example, in 1957, a court ruled that Bennett County is inside the reservation created in 1889. In 2004, a judge decided that a piece of land in Bennett County could be returned to tribal ownership, confirming that the county is indeed within the reservation's boundaries.
People and Communities
Both Lakota and European American people have worked to improve their relationships in recent years. People often refer to themselves as full-bloods, mixed-bloods (usually Native American), and whites. People from different groups often marry each other, and they are working together more.
In the mid-1990s, people in the county held a powwow (a Native American gathering) and a rodeo at the same time. By the 1990s, most people living in the county were of Native American descent. In 2000, Bennett County had the highest percentage of people who identified as both Native American and European American in the U.S., outside of a few specific areas.
Bennett County was in the news in 2014 when a small community called Swett was put up for sale. The two people living there listed six acres of land and all the property for nearly $400,000. By 2016, the price was lowered to $250,000, but it still didn't sell.
