Fort Mandan

Fort Mandan was the name of the encampment which the Lewis and Clark Expedition built for wintering over in 1804-1805. The encampment was located on the Missouri River approximately twelve miles from the site of present-day Washburn, North Dakota, which developed later. The precise location is not known for certain and is believed now to be under water of the river. A replica of the fort has been constructed near the original site.

Construction and conditions

The fort was built of cottonwood lumber cut from the riverbanks. It was triangular in shape, with high walls on all sides, an interior open space between structures, and a gate facing the Missouri River, by which the party would normally travel. Storage rooms provided a safe place to keep supplies. Lewis and Clark shared a room. The men of the Corps of Discovery started the fort on November 2, 1804. They wintered there until April 7, 1805. According to the journals, they built the fort slightly downriver from the five villages of the Mandan and Hidatsa nations.

Mandan

The Mandan are a Native American tribe residing in North Dakota. They are enrolled in the Three Affiliated Tribes of the Fort Berthold Reservation. About half of the Mandan still reside in the area of the reservation; the rest reside around the United States and in Canada.

The Mandan historically lived along the banks of the Missouri River and two of its tributaries—the Heart and Knife Rivers—in present-day North and South Dakota. Speakers of Mandan, a Siouan language, developed a settled, agrarian culture. They established permanent villages featuring large, round, earth lodges, some 40 feet (12 m) in diameter, surrounding a central plaza. While the bison was key to the daily life of the Mandan, they also farmed and actively traded goods with other Great Plains tribes.

Population

The Mandan population was 3,600 in the early 18th century. In 1836, there were over 1,600 fullblood Mandans, but this number was estimated to have dropped to 125 by 1838. In the 1990s, 6,000 people were enrolled in the Three Affiliated Tribes. In the 2010 Census, 1,171 people reported Mandan ancestry. 365 of them were full-bloods, and 806 had partial ancestry.

Lewis and Clark Expedition

The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the first American expedition to cross what is now the western portion of the United States, departing in May 1804, from near St. Louis making their way westward through the continental divide to the Pacific coast.

The expedition was commissioned by President Thomas Jefferson shortly after the Louisiana Purchase in 1803, consisting of a select group of U.S. Army volunteers under the command of Captain Meriwether Lewis and his close friend, Second Lieutenant William Clark. Their perilous journey lasted from May 1804 to September 1806. The primary objective was to explore and map the newly acquired territory, find a practical route across the Western half of the continent, and establish an American presence in this territory before Britain and other European powers tried to claim it.

The campaign's secondary objectives were scientific and economic: to study the area's plants, animal life, and geography, and establish trade with local Native American tribes. With maps, sketches, and journals in hand, the expedition returned to St. Louis to report their findings to Jefferson.

Fortification

Fortifications are military constructions or buildings designed for the defense of territories in warfare, and also used to solidify rule in a region during peace time. Humans have constructed defensive works for many thousands of years, in a variety of increasingly complex designs. The term is derived from the Latin fortis ("strong") and facere ("to make").

From very early history to modern times, walls have been a necessity for cities to survive in an ever changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek Phrourion was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These construction mainly served the purpose of a watch tower, to guard certain roads, passes, and lands that might threaten the kingdom. Though smaller than a real fortress, they acted as a border guard rather than a real strongpoint to watch and maintain the border.

North Dakota

North Dakota (pronunciation: ⁱ/ˌnɔːrθ dəˈkoʊtə/; locally [ˌno̞ɹθ dəˈko̞ɾə]) is the 39th state of the United States, having been admitted to the union on November 2, 1889.

It is located in the Upper Midwestern region of the United States, bordered by the Canadian provinces of Saskatchewan and Manitoba to the north, the states of Minnesota to the east, South Dakota to the south, and Montana to the west. The state capital is Bismarck, and the largest city is Fargo. North Dakota is the 19th most extensive but the 4th least populous and the 4th least densely populated of the 50 United States.

North Dakota has weathered the Great Recession of the early 21st century with a boom in natural resources, particularly a boom in oil extraction from the Bakken formation, which lies beneath the northwestern part of the state. The development has driven strong job and population growth, and low unemployment.

Geography

North Dakota is located in the U.S. region known as the Great Plains. The state shares the Red River of the North with Minnesota on the east; South Dakota is to the south, Montana is to the west, and the Canadian provinces of Saskatchewan and Manitoba are north. North Dakota is situated near the middle of North America with a stone marker in Rugby, North Dakota marking the "Geographic Center of the North American Continent". With an area of 70,762 square miles (183,273 km²), North Dakota is the 19th largest state.
