Context paragraphs:
Baldwin of Avesnes: Baldwin of Avesnes (September 1219 in Oizy – 10 April 1295 in Avesnes) was a son of Bouchard IV of Avesnes and his wife, Margaret II of Flanders.  His parents' marriage was later declared illegal, because his father had already received minor orders.  Baldwin was later declared legitimate by the pope, at the instigation of King Louis IX of France.  In 1246, Baldwin received Beaumont as an apanage.

Shire of Pingelly: The Shire of Pingelly is a local government area in the Wheatbelt region of Western Australia, about 160 km southeast of the state capital, Perth, between the Shires of Brookton and Cuballing along the Great Southern Highway.  The Shire covers an area of 1295 km2 , and its seat of government is the town of Pingelly.

Aragonese conquest of Sardinia: The Aragonese conquest of Sardinia took place between 1323 and 1326.  The island of Sardinia was at the time subject to the influence of the Republic of Pisa, the pisan della Gherardesca family, Genoa and of the genoese families of Doria and the Malaspina; the only native political entity survived was the giudicato of Arborea, allied with the Crown of Aragon.  The financial difficulties due to the wars in Sicily (until 1295), the conflict with the Crown of Castile in the land of Murcia and Alicante (1296-1304) and the failed attempt to conquer Almeria (1309) explain the delay of James II of Aragon in bringing the conquest of Sardinia, enfeoffed to him by Pope Boniface VIII in 1297.

Ilkhanate: The Ilkhanate, also spelled Il-khanate (Persian: ایلخانان‎ ‎ , "Ilkhānān"; Mongolian: Хүлэгийн улс , "Hulagu-yn Ulus"), was established as a khanate that formed the southwestern sector of the Mongol Empire, ruled by the Mongol House of Hulagu.  It was founded in the 13th century and was based primarily in Iran as well as neighboring territories, such as present-day Azerbaijan and the central and eastern parts of present-day Turkey.  The Ilkhanate was originally based on the campaigns of Genghis Khan in the Khwarazmian Empire in 1219–24 and was founded by Hulagu Khan, son of Tolui and grandson of Genghis Khan.  With the fragmentation of the Mongol Empire after 1259 it became a functionally separate khanate.  At its greatest extent, the state expanded into territories that today comprise most of Iran, Iraq, Armenia, Azerbaijan, Georgia, Turkmenistan, Turkey, western Afghanistan, and southwestern Pakistan.  Later Ilkhanate rulers, beginning with Ghazan in 1295, would convert to Islam.

History of Lithuania (1219–95): The history of Lithuania between 1219 and 1295 concerns the establishment and early history of the first Lithuanian state, the Grand Duchy of Lithuania.  The beginning of the 13th century marks the end of the prehistory of Lithuania.  From this point on the history of Lithuania is recorded in chronicles, treaties, and other written documents.  In 1219, 21 Lithuanian dukes signed a peace treaty with Galicia–Volhynia.  This event is widely accepted as the first proof that the Baltic tribes were uniting and consolidating.  Despite continuous warfare with two Christian orders, the Livonian Order and the Teutonic Knights, the Grand Duchy of Lithuania was established and gained some control over the lands of Black Ruthenia, Polatsk, Minsk, and other territories east of modern-day Lithuania that had become weak and vulnerable after the collapse of Kievan Rus'.

Paolo Lanfranchi da Pistoia: Paolo Lanfranchi da Pistoia (Occitan: "Paulo Ianfranchi de Pistoia" ; fl.  1282–1295) was a noted Italian poet who wrote in both the Italian and Occitan languages.  He is thus sometimes described as a troubadour.  A native of Pistoia—he was a major cultural figure of the Duecento there—his sonnets have been praised for their originality.

Scarborough (UK Parliament constituency): Scarborough was the name of a constituency in Yorkshire, electing Members of Parliament to the House of Commons, at two periods.  From 1295 until 1918 it was a parliamentary borough consisting only of the town of Scarborough, electing two MPs until 1885 and one from 1885 until 1918.  In 1974 the name was revived for a county constituency, covering a much wider area; this constituency was abolished in 1997.

Leičiai: Leičiai (singular: leitis) were a distinct social group of the Lithuanian society in the early Grand Duchy of Lithuania subordinate to the Lithuanian ruler or the state itself.  Leičiai were native to the Lietuva Land and formed the core of the Lithuanian society in the pre-state era and during the establishment of the state.  Leičiai made up the majority of the military-economic staff of the state: they enforced state authority in the periphery, protected state borders, and performed various other war-related functions, such as breeding riding horses.  By the 15th and 16th centuries, leičiai were in decline, already losing some of their functions and prestige, and they disappeared as a social class after the implementation of the Wallach Reform.

Cynan ap Maredudd: Cynan ap Maredudd (died 1295) was a Welsh nobleman who assumed leadership of the Welsh revolt of Madog ap Llywelyn in the mid-Wales area in 1294 and 1295.
