Context_1 : The Mysorean invasion of Kerala (1766–1792) was the military invasion of Malabar (northern Kerala), including the territories of the Zamorin of Calicut, by the Muslim "de facto" ruler of the Kingdom of Mysore Hyder Ali. After completing the occupation, Kingdom of Cochin, situated south of Malabar, was made a tributary state of Mysore. The major reason for the occupation of Malabar was the desire to have access to the Indian Ocean ports. The Mysore invasion provided the English East India Company more chances to tighten their grip on the ancient feudal principalities of Malabar and converting Travancore, over whom Mysore Sultans attacked after Cochin, to a mere protected ally Context_2 : The short-beaked common dolphin ("Delphinus delphis") is a species of common dolphin. It has a larger range than the long-beaked common dolphin ("D. capensis"), occurring throughout warm-temperate and tropical oceans, including the Indian Ocean although in smaller quantities than other places they are found. There are more short-beaked common dolphins than any other dolphin species in the warm-temperate portions of the Atlantic and Pacific Oceans. It is also found in the Caribbean and Mediterranean Seas. The short-beaked common dolphin is also abundant in the Black Sea, Gulf of Mexico, and Red Sea. They follow the gulf stream up to Norwegian waters. Seldom do any short-beaked dolphin venture near the Arctic. Context_3 : Moonbabies is a Swedish duo formed in 1997 by vocalists, multi-instrumentalists, producers, and songwriters Ola Frick (Vocals, guitar and various instruments) and Carina Johansson (Vocals and keyboards). Their earliest efforts recalled early Indie/Shoegazer influences by bands like My Bloody Valentine and Cocteau Twins, but with their 2004 album "The Orange Billboard", developed into more sophisticated pop music with a touch of The Beach Boys and The Beatles, as well as experimentation with electronics. The Single/Mini-album War on Sound was released in 2005 and became an immediate indie-anthem and followed success on radio and TV-shows like Grey's Anatomy. In 2007 "Moonbabies at the Ballroom" was released, a somewhat more constructed and song-oriented album including Take me to the Ballroom, Shout it Out, Walking on my Feet and Cocobelle which all were frequently aired on college radio world-wide and included in several TV shows and commercials. Their comeback album Wizards on the Beach was released in April 2015. Context_4 : Mesne (pronounced "mean") profits are sums of money paid for the occupation of land to a person with right of immediate occupation, where no permission has been given for that occupation. The concept is feudal in origin, and common in countries which rely on the English legal system (including many former British colonies). The word is derived from the root word demesne. Context_5 : The recorded history of the Dominican Republic began when the Italian-born navigator Christopher Columbus, working for the Spanish Crown, happened upon a large island in the region of the western Atlantic Ocean that later came to be known as the Caribbean. It was inhabited by the Taíno, an Arawakan people, who variously called their island Ayiti, Bohio, or Quisqueya (Kiskeya). Columbus promptly claimed the island for the Spanish Crown, naming it La Isla Española ("the Spanish Island"), later Latinized to Hispaniola. What would become the Dominican Republic was the Spanish Captaincy General of Santo Domingo until 1821 except for a time as a French colony from 1795 to 1809. It was then part of a unified Hispaniola with Haiti from 1821 until 1844. In 1844, Dominican independence was proclaimed and the republic, which was often known as Santo Domingo until the early 20th century, maintained its independence except for a short Spanish occupation from 1861 to 1865 and occupation by the United States from 1916 to 1924. Context_6 : "D." Miguel Enríquez (c. 1674–1743), was a privateer from San Juan, Puerto Rico who operated during the early 18th century. A mulatto born out of wedlock, Enríquez was a shoemaker by occupation. After working for the governor as a salesman he was recruited to defend Puerto Rico, then a colony of the Spanish Empire, and commanded a small fleet that intercepted foreign merchant ships and other vessels dedicated to contraband. These outlaws were thriving in the waters of the Caribbean Sea and the Atlantic Ocean, notably in the areas surrounding Saint Thomas, Curaçao and Jamaica. Operating during the height of the Golden Age of Piracy, his fleet was also credited with controlling the proliferation of buccaneers in the region. However, he was considered a pirate himself by the enemies of Spain, since it was common practice of the government to ignore when foreign ships were attacked. After some time operating independently, Enríquez received a letter of marque and reprisal from the Spanish Crown, this was a special permit granting him the privileges of a privateer. Corsairs from Puerto Rico were often called "guardacostas", or "coast guards." They operated in the same fashion as any other pirate, the only difference was that they did it in the name of Spain, protecting imperial trade restrictions. Employing a systematic approach, Enríquez was able to become the most successful and influential Puerto Rican of his time. However, despite this, he was never able to gain the acceptance of the higher social classes, something that he strived to earn throughout his life. Context_7 : Nabetari is a Gilbertese (Pacific Islands) native who impressed several senior Allied officers with his successful attempt on or about 4 April 1944 to escape from the Second World War Japanese occupation of the Nauru. Nabetari made a record ocean voyage in a small fishing canoe to the Gilbert Islands, about 240 miles to the east. In November, after seven months on the ocean, he was washed up on the reef of the Ninigo Island close to Manus, the largest of the Admiralty Islands archipelago. He was later flown to Tarawa to provide information about the Japanese troops on the Nauru. Nabetari covered a total of 1,500 miles during his escape. Context_8 : Hall is a common surname of English origin. Hall means "kind" and "forgiving". This originates from the belief that Vikings were eternally benevolent to those that worked within their halls. The name was used to indicate the main occupation of the individual, in a role such as a servant or chamberlain. Hall is the 22nd most common surname in the United Kingdom. Within the United States, it is ranked as the 26th most common surname. Context_9 : We Are the Ocean were a four-piece English rock band from Loughton, Essex, consisting guitarist, vocalist Liam Cromby, bass guitarist Jack Spence, guitarist Alfie Scully and drummer Tom Whittaker. Vocalist Dan Brown left the band in 2012. They are signed to Hassle Records in the United Kingdom and SideOneDummy Records in the United States. Context_10 : The Convention of Balta Liman of 1 May 1849 was an agreement between the Russian Empire and the Ottomans regulating the political situation of the two Danubian Principalities (the basis of present-day Romania), signed during the aftermath of the Revolutions of 1848. Moldavia, which had been placed under Russian occupation in late spring 1848 following a revolutionary attempt, and Wallachia, where a liberal Provisional Government had briefly assumed power before facing a common Ottoman-Russian reaction, were confirmed their previous status of Ottoman suzerainty and Russian protectorate (first established in 1831–32 by the "Regulamentul Organic"). Minor provisions were added, signifying a relative increase in Ottoman influence—namely, "hospodars" were no longer elected by the local National Assemblies for life, and instead appointed by the Sublime Porte for seven-year terms. A common military presence was maintained until 1851. The document led to the appointment of Barbu Dimitrie Ştirbei as hospodar of Wallachia and Grigore Alexandru Ghica as hospodar of Moldavia. The Convention was rendered void by the Crimean War (during which the Principalities fell under Austrian occupation), and the statutory system itself was annulled by the 1856 Treaty of Paris. fact_1 : Moonbabies is a Swedish duo formed in 1997 by vocalists, multi-instrumentalists, producers, and songwriters Ola Frick (Vocals, guitar and various instruments) and Carina Johansson (Vocals and keyboards). fact_2 : We Are the Ocean were a four-piece English rock band from Loughton, Essex, consisting guitarist, vocalist Liam Cromby, bass guitarist Jack Spence, guitarist Alfie Scully and drummer Tom Whittaker.
