  Title: Roop's Fort
  Passage: Roop's Fort, also known as Roop's Trading Post, Fort Defiance, and Roop House, is a historic building in Susanville, California.  The building, which was built in 1854 by Isaac Roop, was the first building built by white settlers in Lassen County.  The fort was originally a trading post for westbound migrants and was the first post west of Fort Hall in Idaho.  The building also served as the capitol of the short-lived Nataqua Territory, a territory created in 1856 to avoid California tax collectors.  The territory was incorporated into Roop County, Nevada, named for Isaac Roop, in 1861.  California and Nevada entered into a border dispute known as the Sagebrush War over the Susanville area in 1863, and Roop's Fort served as a fort for the Nevadans during the skirmish.  California won the war, and Roop's Fort became part of Lassen County in 1864.
  Title: Cushnoc Archeological Site
  Passage: The Cushnoc Archeological Site, also known as Cushnoc (ME 021.02) or Koussinoc or Coussinoc, is an archaeological site in Augusta, Maine that was the location of a 17th-century trading post operated by English colonists from Plymouth Colony in present-day Massachusetts.  The trading post was built in 1628 and lies on the Kennebec River.  It is adjacent to Fort Western, an 18th-century stockade fort around which the city of Augusta grew.  The site is significant as it provides a window into trading, living, and construction practices in the early period of colonial settlement in New England.  It was declared a National Historic Landmark in 1993.
  Title: Fort Apollonia
  Passage: Fort Apollonia is a fort in Beyin, Ghana.  The name Apollonia was given to the area by a Portuguese explorer who sighted the place on the Feast of Saint Apollonia, 9 February.  The Swedes established a trading post at Apollona as part of the Swedish Gold Coast between 1655-1657.  In 1691, a British trading post was erected at this site, which between 1768 and 1770 was extended into a fort.  After the abolition of slave trade, the fort was abandoned in 1819, but it was again occupied from 1836 onwards.
  Title: Bowlin's Old Crater Trading Post
  Passage: Bowlin's Old Crater Trading Post is a former trading post which was located along historic U.S. Route 66 in Bluewater, New Mexico.  The trading post was built in 1954 by Claude Bowlin.  Bowlin had traded with local Navajo since 1912, and he built his first trading post at the site in 1936.  The store's name came from a volcanic crater that drew tourists to the area.  While the trading post initially served the Navajo, it soon served tourists as well due to increased traffic on Route 66.  Inspired by his success, Bowlin built a chain of stores throughout New Mexico, which became Bowlin Travel Centers, Inc. In 1954, Bowlin replaced his original trading post with the current building.
  Title: Fort Alexander, Manitoba
  Passage: Fort Alexander -"Sagkeeng" Ojibway (mouth of the river) is a community in Manitoba, Canada, located on the Sagkeeng First Nation, on the south bank of the Winnipeg River.  The Sagkeeng area, or the mouth of the Winnipeg River, was originally settled with native camps used for fishing, hunting, and trade.  During the fur trade era, La Vérendrye built a trading post, named Fort Maurepas, on the north side of the river; this post was abandoned near the end of the French period.  In the year 1792, a clerk for the North West Company, Toussaint Lesieur, built a post on the south side, which became an important provisioning post for the canoe brigades.  Bags of pemmican, brought from the North West Company's posts on the upper Assiniboine, were stored here and taken as needed by the canoe brigades passing between Grand Portage (later, Fort William) and the far northwest.  This post was usually referred to as Fort Bas de la Rivière, because of its location at the bottom of Winnipeg River, and it seems to have functioned as the capital of the Company's Lake Winnipeg district.  The Hudson's Bay Company operated its own post here for a few years between 1795 and 1801.  In 1807, the North West Company partner Alexander MacKay rebuilt the post on a nearby site.  Beginning in 1808, the new post was known as Fort Alexander.  After the Northwest and Hudson's Bay Companies merged in 1821, Fort Alexander was operated as a trading post for the natives in the region.
  Title: Fort Union Trading Post National Historic Site
  Passage: Fort Union Trading Post National Historic Site is the site of a partially reconstructed trading post on the Missouri River and the North Dakota/Montana border, twenty-five miles from Williston, North Dakota.  It is one of the earliest declared National Historic Landmarks in the United States.  The fort, possibly first known as Fort Henry or Fort Floyd, was built in 1828 or 1829 by the Upper Missouri Outfit managed by Kenneth McKenzie and capitalized by John Jacob Astor's American Fur Company.
  Title: Fort Robidoux
  Passage: Fort Robidoux, a fur trading post also known as Fort Uintah and Fort Winty, was located at the junction of the Uintah and Whiterocks rivers in the Uinta Basin of northeastern Utah.  It was founded in 1832 after Antoine Robidoux bought out the Reed Trading Post that had been in operation at that site since 1828.  Robidoux had traded for beaver pelts in the Uintah Basin region as early as 1824.  By 1828 he had established his first trading post in the intermountain corridor of the western slopes of the Rocky Mountains on the Gunnision River near present-day Delta, Colorado.  Robidoux took out Mexican citizenship and married Carmel Benevedes, the adopted daughter of the governor of New Mexico, that same year.  This enabled him to obtain a Mexican trading and trapping license.
  Title: Dutch Slave Coast
  Passage: The Dutch Slave Coast (Dutch: "Slavenkust") refers to the trading posts of the Dutch West India Company on the Slave Coast, which lie in contemporary Ghana, Benin, Togo and Nigeria.  The primary purpose of the trading post was to supply slaves for the plantation colonies in the Americas.  Dutch involvement on the Slave Coast started with the establishment of a trading post in Offra in 1660.  Later, trade shifted to Ouidah, where the English and French also had a trading post.  Political unrest caused the Dutch to abandon their trading post at Ouidah in 1725, now moving to Jaquim, at which place they built Fort Zeelandia.  By 1760, the Dutch had abandoned their last trading post in the region.
  Title: Tsurukaitu
  Passage: Tsurukhaitu was a trading post along the Russo-Chinese border north of Peking during the eighteenth century.  For background see Kyakhta trade.  It was never successful because the Kyakhta route was easier than the long trek east from Lake Baikal.  The trade route ran from Irkutsk east to Tsurukhaitu (about 7 weeks) and southeast through Tsitsihar and the Shanhai Pass to Peking, over 650 miles longer than the Kyakhta route.  By the Treaty of Kyakhta (1727) all official trade was to be conducted through border posts near the future Kyakhta and Tsurukhaitu.  Once the Treaty was completed Sava Vladislavich made elaborate plans for the two new posts, Tsurukhaitu being somewhat smaller.  Previously trade in the area was from Nerchinsk to Tsitsihar.  The site was chosen in 1728 by Temofei Burtsov, a commissar of the Argun silver mines(sic) and a Chinese officer.  Construction did not begin until 1736 because of obstruction by a local official and the distance that lumber had to be carried.  The site was poor, firewood was over 25 miles distant and it was frequently flooded by the Argun River.  In 1756 to fort was moved downstream to a new site.  Unlike Kyakhta, the Manchus never erected a fort on their side of the border.  Instead it was visited for about a month in early summer by merchants and border inspectors.  In 1733 the official caravan tried to return by Tsurukhaitu rather than Kyakhta.  Goods were spoiled due to lack of covered storage at the fort, they had difficulty finding laborers and it took all summer to travel west to Irkutsk.  Maximum Russian exports at Tsurukhaitu were 2,845 rubles in 1768.  The Kyakhta trade grew from 300,000 rubles in 1727 to 5,000,000 in 1805.
