In 1749, the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country. The grant required that it settle 100 families in the territory and construct a fort for their protection. But the territory was also claimed by Pennsylvania, and both colonies began pushing for action to improve their respective claims. In 1750, Christopher Gist explored the Ohio territory, acting on behalf of both Virginia and the company, and he opened negotiations with the Indian tribes at Logstown. He completed the 1752 Treaty of Logstown in which the local Indians agreed to terms through their "Half-King" Tanacharison and an Iroquois representative. These terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania. By the late 17th century, the Iroquois had pushed many tribes out of the Ohio Valley, and they laid claim to it as their hunting ground by right of conquest. The War of the Austrian Succession  formally ended in 1748 with the signing of the Treaty of Aix-la-Chapelle, which was primarily focused on resolving issues in Europe. The issues of conflicting territorial claims between British and French colonies were turned over to a commission, but it reached no decision. Frontier areas were claimed by both sides, from Nova Scotia and Acadia in the north to the Ohio Country in the south. The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland.

What happened first: Treaty of Logstown or Treaty of Aix-la-Chapelle?
A: Treaty of Aix-la-Chapelle

Since 1444 Si Jifa had repeatedly sent tribute to Ming asking for pardon to no avail. In March 1449, a combined army of 150,000 soldiers was amassed, and the fourth and final campaign to extirpate the Mong Mao threat was launched under the supervision of Wang Ji. The army quickly marched on Mong Yang, which harbored Si Jifa, and captured their strongholds. However Si Jifa managed to escape yet again, and the campaign ended inconclusively with the ruling Shan elite allowed to remain in Mong Yang so long as they never returned to Mong Mao. Sources disagree as to how Si Jifa met his end. One source claims he died in combat in 1449, another says he was captured by the king of Ava and held captive in exchange for Ming territory, and one Shan chronicle claims he reigned for another fifty years. While Mong Mao had been defeated and pacified, Si Jifa's son Si Hongfa continued to rule in Mong Yang and his successors would eventually go on to invade Ava in 1527. So in practice Si Lunfa's family survived as rulers in the neighboring state of Mong Yang under the close observation of Ming. The fourth campaign was also marred by lack of discipline, inefficient administration, and mismanagement of resources. On the first day of mobilization, the entire 150,000 strong army started marching all at once, and many were trampled to death. Food supplies were mismanaged and assigned to individual carriers disproportionate to their weight, and no proper plan for their distribution existed. Some soldiers committed suicide due to the conditions prevalent in the army.
