Input: Consider Input: Question: Which states aided the Latin Empire under the benner "Crusader States"? Passage:The Nicaean–Latin wars were a series of wars between the Latin Empire and the Empire of Nicaea, starting with the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. The Latin Empire was aided by other Crusader states established on Byzantine territory after the Fourth Crusade, as well as the Republic of Venice, while the Empire of Nicaea was assisted occasionally by the Second Bulgarian Empire, and sought the aid of Venice's rival, the Republic of Genoa. The conflict also involved the Greek state of Epirus, which also claimed the Byzantine inheritance and opposed Nicaean hegemony. The Nicaean reconquest of Constantinople in 1261 AD and the restoration of the Byzantine Empire under the Palaiologos dynasty did not end the conflict, as the Byzantines launched on and off efforts to reconquer southern Greece (the Principality of Achaea and the Duchy of Athens) and the Aegean islands until the 15th century, while the Latin powers, led by the Angevin Kingdom of Naples, tried to restore the Latin Empire and launched attacks on the Byzantine Empire.

Input: Consider Input: Question: In what year was the Hank Williams song that helped The Midnight Ghost Train get their name released? Passage:The Midnight Ghost Train was originally formed by Steve Moss in Buffalo, NY. The band's name comes partially from a Hank William's song lyric in I'm So Lonesome I Could Cry. TMGT's first release was "Johnny Boy EP" in 2008, and in 2009 they self-released their first full length album which was self-titled. The album was self-recorded in their home studio after the band relocated to Kansas. They followed up with their 2012 album "Buffalo", released on Karate Body Records. It was recorded entirely analog by Dave Barbe in Athens, Georgia. Displaying the band's delta blues influences, the album features a Lead Belly cover of Cotton Fields done a cappella. In 2013, TMGT performed at the Roadburn Festival in Tilburg, Netherlands, and released "Live at Roadburn 2013" shortly thereafter. After losing their previous bass player, they went through several lineup changes before finding permanent bassist Mike Boyne. In 2014, TMGT signed with the Austrian based metal label, Napalm Records, which released TMGT's "Cold Was The Ground" on February 28, 2015. The album had a much faster tempo than previous releases, with more emphasis on song construction. The release boosted their popularity allowing them to appear at major festivals such as Hellfest and Graspop Metal Meeting. Napalm released their fourth full length album "Cypress Ave." on July 28, 2017. Once again progressing into a more mature sound with a wide array of genres. Including a hip hop track featuring Sonny Cheeba from Camp Lo. TMGT has been most commonly described as hard rock, and related to bands like Kyuss, Black Sabbath, and Clutch. The band built the majority of their fan base from consistent touring, and exciting live performances. In 2018 TMGT called it quits in order to focus more on family life, after playing their last show at the Maryland Doom Fest.
