Passage: Sporadic and isolated outbursts by Tibetans against the Chinese continued especially during the unrest between September 1987 until March 1989 in the Tibetan areas of the PRC. But it wasn't until 2008 that a large-scale and coordinated uprising erupted coinciding with international protests accompanying the Olympics torch relay that would end in Beijing where the 2008 Summer Olympics were held. What originally began as an annual observance of Tibetan Uprising Day turned into street protests by large numbers of monks from various monasteries for several days. Crowd control and arrests escalated the tensions eventually setting off a riot by thousands of Tibetans in the Ramoche section of Lhasa on March 14, 2008. When the police fled the scene, rioters looted and burned more than 1200 Chinese shops, offices, and residences and set fire to nearly 100 vehicles. In the end, an estimated 22 were dead and 325 injured, mostly Han. Total damage was estimated at $40 million USD. Eventually the paramilitary People's Armed Police were sent in and 50-100 Tibetan rioters were killed before things quieted down. Meanwhile, in the Gansu Province, a demonstration by 400 monks were met with force that ignited riots by more than 5000 Tibetans who again burned down the establishments of local Han and Hui people before security forces arrived.
Question: When were an estimated 325 Tibetan rioters injured?

Passage: When the railroad was extended through Madison in 1875, larger mills were built. The first Madison Woolen Mill was constructed in 1881 near the bridge between Madison and Anson, with the firm's second mill built nearby in 1887. In 1890, the Manufacturing Investment Company built a sulfite mill, but it failed. It was taken over in 1899 by the Great Northern Paper Company, which rebuilt the plant to produce wood pulp and paper. Like many New England textile manufacturers, the town's woolen mills eventually went out of business, but the pulp and paper mill remains today as the Madison Paper Industries which will close by May 2016 due to low demand for supercalender paper and Canadian competition. In 1901, Lakewood Summer Theatre opened in East Madison on the western side of Lake Wesserunsett. Since 1967 it has been the official summer theatre of Maine, and the oldest continually operating summer theatre in America.

Passage: The conflict between Novgorod and Teutonic Knights began in 1210, when the knights attacked the Estonians. Novgorod campaigned against the Livonians in 1217, 1219, 1222, and 1223, facing repeated failure. In 1224, the knights captured Dorpat . Soon after the capture of Dorpat, an internal conflict arose in Novgorod. The townspeople refused to help in the fight against the knights. Soon, a split occurred among the Novgorod nobles. Expelled from the city, the nobles and the Knights captured Izborsk in 1233, but soon were expelled from the city by the Pskov army. A year later, Yaroslav Vsevolodovich of Novgorod returned to the Livonian lands and devastated the outskirts of the town Odenpa, triumphing over Emajõe and forcing the Livonians to sign a peace agreement. In 1236, Lithuania had lost a Great Master of the Order of the Sword Volquin von Winterstein, and Pope Gregory IX gave his consent to the Union of the Order of the Sword with the Teutonic Knights. The master of the Order was Hermann von Balk. In December 1237, Pope Gregory IX proclaimed the second crusade against Finland. Danish king Waldemar II and the joint Masters of the Order agreed to divide Estonia and attacked Baltic Russia in June 1238 in collaboration with the Swedes. The Russian lands were weakened by the Mongol invasion.
