Oto in 1830. The Ioway ceded the last of their Iowa lands in 1838. The Winnebago and Potawatomi, who had only a short time before been removed to Iowa, were yet again removed and had left Iowa by 1848 and 1846, respectively. The last remaining group, the Sioux, ceded their last Iowa land via an 1851 treaty with the United States, which they completed in 1852. Today, Iowa is still home to one American Indian group, the Meskwaki, who reside on the Meskwaki Settlement in Tama County. After most Sauk and Meskwaki members had been removed from the state, some Meskwaki tribal members, along with a few Sauk, returned to hunt and fish in eastern Iowa. The Indians then approached Governor James Grimes with the request that they be allowed to purchase back some of their original land. They collected $735 for their first land purchase and eventually they bought back approximately 3,200 acres (13 km²). After purchasing some of their land back, the Iowa Legislature fought for the Meskwaki tribe to receive an annual payment from the Federal Government. This took ten years to be resolved. Iowa's first Euro-American settlers The Black Hawk Purchase opened up the lands of Iowa to settlers for the first time, and "official" settlement began pursuant to this on June 1, 1833. At the time of the opening of these lands, there were likely only 40-50 Americans then settled in Iowa. Many of those who settled before June 1, 1833 were at the Native American villages of Ahwipetuk (now Nashville) and Puckeshetuk (now Keokuk). Many of the pre-1833 settlers were trappers and traders, though some came to mine. The earliest of these Euro-American settlers were French, as the land was originally under French jurisdiction. They came to trade fur, preach, discover mines, and explore, and were generally transient. A few, however, secured land grants and settled in the area when Iowa was under Spanish jurisdiction. The first settler appears to have been Julien Dubuque, a French-Canadian man who arrived at the lead mines near modern-day Dubuque in 1787. He obtained permission to mine the land from the Meskwaki, who generously stated that he could work the mines "as long as he shall please." Additional early Spanish grants include a grant of land near Montrose to Louis Honore in 1799, and of land near McGregor to Basil Giard in 1796. As previously stated, Euro-American settlement
