input: After returning to Grand Rapids in 1946, Ford became active in local Republican politics, and supporters urged him to take on Bartel J. Jonkman, the incumbent Republican congressman. Military service had changed his view of the world. "I came back a converted internationalist", Ford wrote, "and of course our congressman at that time was an avowed, dedicated isolationist. And I thought he ought to be replaced. Nobody thought I could win. I ended up winning two to one." During his first campaign in 1948, Ford visited voters at their doorsteps and as they left the factories where they worked. Ford also visited local farms where, in one instance, a wager resulted in Ford spending two weeks milking cows following his election victory. Ford was a member of the House of Representatives for 25 years, holding the Grand Rapids congressional district seat from 1949 to 1973. It was a tenure largely notable for its modesty. As an editorial in The New York Times described him, Ford "saw himself as a negotiator and a reconciler, and the record shows it: he did not write a single piece of major legislation in his entire career." Appointed to the House Appropriations Committee two years after being elected, he was a prominent member of the Defense Appropriations Subcommittee. Ford described his philosophy as "a moderate in domestic affairs, an internationalist in foreign affairs, and a conservative in fiscal policy." Ford was known to his colleagues in the House as a "Congressman's Congressman". In the early 1950s, Ford declined offers to run for either the Senate or the Michigan governorship. Rather, his ambition was to become Speaker of the House, which he called "the ultimate achievement. To sit up there and be the head honcho of 434 other people and have the responsibility, aside from the achievement, of trying to run the greatest legislative body in the history of mankind ... I think I got that ambition within a year or two after I was in the House of Representatives".

Problem: Background: Timur was born in Transoxiana near the city of Kesh (modern Shahrisabz, Uzbekistan) some 80 kilometres (50 mi) south of Samarkand, part of what was then the Chagatai Khanate. His father, Taraqai, was a minor noble of the Barlas, a Mongolian tribe that had been turkified in many aspects. According to Gerard Chaliand, Timur was a Muslim, and he saw himself as Genghis Khan's heir. Though not a Borjigid or a descendent of Genghis Khan, he clearly sought to invoke the legacy of Genghis Khan's conquests during his lifetime.
Context: Timur spent the next 35 years in various wars and expeditions. He not only consolidated his rule at home by the subjugation of his foes, but sought extension of territory by encroachments upon the lands of foreign potentates. His conquests to the west and northwest led him to the lands near the Caspian Sea and to the banks of the Ural and the Volga. Conquests in the south and south-West encompassed almost every province in Persia, including Baghdad, Karbala and Northern Iraq. One of the most formidable of Timur's opponents was another Mongol ruler, a descendant of Genghis Khan named Tokhtamysh. After having been a refugee in Timur's court, Tokhtamysh became ruler both of the eastern Kipchak and the Golden Horde. After his accession, he quarreled with Timur over the possession of Khwarizm and Azerbaijan. However, Timur still supported him against the Russians and in 1382 Tokhtamysh invaded the Muscovite dominion and burned Moscow. In 1395 Tamerlane reached the frontier of Principality of Ryazan, took Elets and advancing towards Moscow came near the banks of the Don River. Great Prince Vasily I of Moscow went with an army to Kolomna and halted at the banks of the Oka River. The clergy brought the famed Theotokos of Vladimir icon from Vladimir to Moscow. Along the way people prayed kneeling: "O Mother of God, save the land of Russia!" Suddenly, Tamerlane's armies retreated. In memory of this miraculous deliverance of the Russian Land from Tamerlane on August 26, the all-Russian celebration in honor of the Meeting of the Vladimir Icon of the Most Holy Mother of God was established.
Question: What happened during the period of expansion?
Answer: 1395 Tamerlane reached the frontier of Principality of Ryazan, took Elets and advancing towards Moscow came near the banks of the Don River.

Question: The Nitty Gritty Dirt Band, an American country rock band, has existed in various forms since its founding in Long Beach, California in 1966. The group's membership has had at least a dozen changes over the years, including a period from 1976 to 1981 when the band performed and recorded as the Dirt Band. Constant members since the early times are singer-guitarist Jeff Hanna and drummer Jimmie Fadden. Multi-instrumentalist John McEuen was with the band from 1966 to 1986 and returned during 2001 departing once again in November 2017.

The Nitty Gritty Dirt Band was founded around 1966 in Long Beach, California by singer-guitarist Jeff Hanna and singer-songwriter guitarist Bruce Kunkel who had performed as the New Coast Two and later the Illegitimate Jug Band. Trying, in the words of the band's website, to "figure out how not to have to work for a living," Hanna and Kunkel joined informal jam sessions at McCabe's Guitar Shop in Long Beach. There they met a few other musicians: guitarist/washtub bassist Ralph Barr, guitarist-clarinetist Les Thompson, harmonicist and jug player Jimmie Fadden, and guitarist-vocalist Jackson Browne. As Nitty Gritty Dirt Band, the six men started as a jug band and adopted the burgeoning southern California folk rock musical style, playing in local clubs while wearing pinstripe suits and cowboy boots. Their first paying performance was at the Golden Bear in Huntington Beach, California. Browne was in the band for only a few months before he left to concentrate on a solo career as a singer-songwriter. He was replaced by John McEuen on banjo, fiddle, mandolin, and steel guitar. McEuen's older brother, William, was the group's manager, and he helped the band get signed with Liberty Records, which released the group's debut album, The Nitty Gritty Dirt Band during 1967. The band's first single, "Buy for Me the Rain," was a Top 40 success, and the band gained exposure on The Tonight Show Starring Johnny Carson, as well as concerts with such disparate artists as Jack Benny and The Doors. A second album, Ricochet, was released later during the year and was less successful than their first. Kunkel wanted the band to "go electric", and include more original material. Bruce left the group to form WordSalad and Of The People. He was replaced by multi-instrumentalist Chris Darrow. By 1968, the band adopted electrical instruments anyway, and added drums. The first electric album, Rare Junk, was a commercial failure, as was their next, Alive. The band continued to gain publicity, mainly as a novelty act, making an appearance in the 1968 film, For Singles Only, and a cameo appearance in the 1969 musical western film, Paint Your Wagon, performing "Hand Me Down That Can o' Beans". The band also played Carnegie Hall as an opening act for Bill Cosby and played in a jam session with Dizzy Gillespie.
