The tögrög or tugrik (Mongolian: төгрөг, tögrög) (sign: ₮; code: MNT) is the official currency of Mongolia. It was historically subdivided into 100 möngö (мөнгө). Currently the lowest denomination in regular use is the 10-tögrög note and the highest is the 20,000-tögrög note. Currency sign is U+20AE ₮ tugrik sign.

In 2010, the tögrög was the best-performing currency world-wide.

The tögrög was introduced on December 9, 1925 at a value equal to one Soviet ruble, where one ruble or tögrög was equal to 18 grams (0.58 ozt) of silver. It replaced the Mongolian dollar and other currencies and became the sole legal currency on April 1, 1928.

Möngö coins are not in circulation as currency any longer, as they are of negligible value. They are sold to tourists and as novelties and collectibles now.

During socialism, the tögrög coin denominations were 1, 2, 5, 10, 15, 20, 50 möngö, and 1 tögrög. After the Mongolian People's Republic came to an end in 1990 and inflation surged, the möngö coins were abandoned and larger tögrög values introduced.

Genghis Khan (/ˈɡɛŋɡɪs ˈkɑːn/ or /ˈdʒɛŋɡɪs ˈkɑːn/,Mongol: [tʃiŋɡɪs xaːŋ] ( listen); 1162? – August 1227), born Temujin, was the founder and Great Khan (emperor) of the Mongol Empire, which became the largest contiguous empire in history after his death.

He came to power by uniting many of the nomadic tribes of northeast Asia. After founding the Mongol Empire and being proclaimed "Genghis Khan", he started the Mongol invasions that resulted in the conquest of most of Eurasia. These included raids or invasions of the Kara-Khitan Khanate, Caucasus, Khwarezmid Empire, Western Xia and Jin dynasties. These campaigns were often accompanied by wholesale massacres of the civilian populations – especially in Khwarezmia. By the end of his life, the Mongol Empire occupied a substantial portion of Central Asia and China.

Before Genghis Khan died, he assigned Ögedei Khan as his successor and split his empire into khanates among his sons and grandsons. He died in 1227 after defeating the Western Xia. He was buried in an unmarked grave somewhere in Mongolia at an unknown location. His descendants went on to stretch the Mongol Empire across most of Eurasia by conquering or creating vassal states out of all of modern-day China, Korea, the Caucasus, Central Asian countries, and substantial portions of modern Eastern Europe, Russia and the Middle East. Many of these invasions resulted in the large-scale slaughter of local populations, which have given Genghis Khan and his empire a fearsome reputation in local histories.
