only on c-span3. this year, c-span's touring cities across the country, exploring american history. my look at our visit to pittsburgh, pennsylvania. you're watching american history tv, all weekend, every weekend on c-span3. today, the triangle of brown encompasses what is now the park but in the 18th century it was going to be the home of one of the largest british military installations in north america. the diorama in front of it represents what pittsburgh would have looked like in the mid-1760's. look at tod place to understand the history of why this triangle of land inside of the park today was so important

in the 18th century and into the 19th century for a lot of reasons. the biggest is just the location along the two rivers, the allegheny on one side. they come together to form the ohio. is so important is certainly during the 18th century and the mid-18th century, the allegheny takes you all the way up to french canada. you can also from the ohio, travel up smaller streams and make it a great theory -- make it up to lake erie. ittish america, the heart of along the potomac. those two rivers are important enough but want to get on the ohio, you can continue and basically -- once you get on the ohio, you can continue and basically go to new orleans. you can control the whole region in essence, militarily you can

keep your enemy for moving large amounts of men and materials along the river. ohio and pittsburgh are the toeway to the west, prior st. louis being the gateway. basically pittsburgh and fort pitt or the gateway to the west. there were a series of fort sill here, the first built by the english in 1754. though more than a storehouse with a stockade -- little more than a storehouse with a stockade around the outside. it had been intended to be called fort prince george but it is often called french fort after the man in charge -- trench fort after the man in charge. before the laws were set in the ground, the french arrived with a force of 500 men and told the englishman that were here with their indian allies that they

needed to go and associated. without a shot fired the french took control of the four in 1764. they began work on a larger fort called fort duchense. it was a very small wooden palisade. it was not incredibly strong. we actually had to add on to it. it was barely large enough to contain the men that were stationed there, but it did represent to the english very forcefully that the french were in the central ohio and it was indians symbol to the in the region. the english have not given up toe to be controlled the -- controlled the point and they made it with an army of several thousand men. this time it was the french are who decidedeave --

urnt and and b destroyed the fort. fort pitt was this big fort. it was that much larger. flooding in the 1760's damaged the bastions very severely that arthen, causing e a series of blockhouses to be built to reinforce the area. the last of these still survives and is actually still in point built in 1764. what we have is a reconstructed barracks where they would have lived in. one of the interesting things about the soldiers who served was a very diverse group of men. so originally there was a group that was intended to be raised

in the colony called the royal american regiment, but they were unable to raise enough troops here so they were recruiting in europe. a lot of ethnic germans ended up here, serving at fort pitt. time, there were scottish troops, irish troops. men from all over great britain. start,ly right from the it was a very diverse ethnic community justin fort pitt pittf -- just in fort itself. that is not counting the native nations that were active here. one of our cabins is a constructed fur trader cabin. one of the roles that they played was regulating before inflated trade with the native americans in the region. before trade was extremely fur trade washe

extremely important for the region. in any given year, 200,000 or hides would go through fort pitt alone. it was very important it was an honest trade so having the military outpost also regulates the fur trade and controls, to make sure that the traders were the scrupulous with the natives which could cause diplomatic problems. in this area of the museum, we discussed the motivations and the tactics and the weapons of the three different powers struggling for control of western pennsylvania during the indian war. we have the french and their native allies against the british and their native allies. struggling for control of the forts and ohio country.

french began to press their claim and built a series of forts. british built fort prince george and struggled for control of the point. the native indians, some found themselves aligned with the french and some with the british. of course, ultimately they were the ones that suffer to the most both -- suffered the most from both. although there was not a declared war, there was an ongoing tension on the frontier, and again, some indian tribes nations allied themselves with the french or the british. there was the possibility of traders being ambushed and robbed. at times ofurders indians. so there was a lot of potential for larger conflict that boiled 1756, when thein

french and indian war really kicked off in full force. it is described as the seven year's war, we often refer to it as the french and a conflict that was sometimes described as the first world war. clear that became the english were going to essentially be victorious in this conflict. and theugh the french british signed a peace treaty in 1763, the american indians were left out of that equation, and there was a lot of animosity with the various tribes are supported either side, so in 1763, the indians in the ohio country and the great lakes conflictgether in a often called pontiac's war or pontiac's rebellion. basically they struck almost every frontier english fort in

that region simultaneously almost and manage to destroy a large part of the british holdings on the frontier. fort pitt itself was laid siege of 1763 andmmer really only fort pitt and fort detroit survived the onslaught. in 1764, henry n expedition from fort pitt into ohio country -- led an expedition from fort pitt into ohio country to wrap up the loose ends of pontiac. hundreds of white captives have been taken during the conflict were assimilated into american indian culture, and the english were returning -- demanding the return of those captives. the bulk of them came to fort pitt and families came from all over to reclaim captives. in some cases these were children, in some cases adults, in some cases have been held by

indians for so long that they no longer knew what their identities were. the charters of virginia and pennsylvania were vague enough to include the area of western pennsylvania that fort pitt is located in. if we think back about the history of the region, although pennsylvania was often involved in the diplomatic side of things and administered the civil courts and actions of fort pitt, when george washington came to the ohio country to tell the french to get out, the came as a representative of the came asf virginia -- he a representative of the colony of virginia. the first fort was built at the request of the governor of virginia. the revolt of the military aspects of governing this area. they wereies -- involved in the military aspects of governing this area. both colonies thought it was

their own. to1763, lord dunmore began have a plan to act on that. in 1774, his representatives seize the civil government here and pittsburgh became virginia and remains virginia through the years of the american revolution. at the end of lord dunmore's 's demand bytt soldiers from virginia. of course, this is taking place in the fall of 1774. in the spring of 1775, of inrse, concord and lexington the first shots and rumbling of the american revolution -- lexington and concorde and the first shots and rumblings of the american revolution. there are people who support king george, people who support the patriot cause. fort pitt again gets revitalized

and reoccupied as an american fort during the revolutionary war. one of our key artifacts we have on display here is the flag of john proctor's battalion from west moreland county. it was a flag created early in the 1770's and it is kind of important for several reasons. one is that the symbolism on it of the coiled rattlesnake and the inscription, "don't fret on me." -- ted on me." me."ed on the only surviving rattlesnake flag and we believe it may have been the first ever created. it is interesting symbolism where we have the coiled snake, and the rattlesnake is unique to north america and it looks

towards the canton of the flag which is a british union jack. warning thelearly mother country to respect the rights of the americans or suffer the consequences. until july 4, essentially, 1776, much of the effort of the american revolution was actually reconciliation with the mother country, which is why we have a flag of the revolutionary war era that has a british flag on it itself. only a handful of flags survived from the revolutionary war era. this one is extremely fragile. it was painted in oil on silk. you see the light going on and off. it is very light sensitive. we have a motion detector and change it out with a reproduction to reduce the stress.

close of the american revolution, congress has never made a provision for the standingarmy, so the army was disbanded. by the mid-1780's, basically the entire army was located in two places, west point in new york and here at fort pitt. began to be a very expected proposition to maintain. was several decades old. the buildings that one would have started to dk. the earthworks have slumped and suffered. be an activesed to military posts and more of a military depot. fort pitt was decommissioned in 1791. a lot of it was torn down and the materials were used, the ditches began to be filled. pitte early 1800s, fort

became a memory to pittsburgh. today we see the interpretation of fort pitt in the early military history on the force of key too as being understanding why pittsburgh exists today, and to understand s key influence on the settling of the west. this weekend, we are featuring history of pittsburgh, pennsylvania. together with our comcast cable partners. andn more about pittsburgh other stops on the cities tour at c-span.org/cities tour. are watching american history tv, all weekend, every weekend on c-span3. >> monday night on "the communicators." copyrightthat any
