Long ago, a group of people built a new land. 
Long ago, the Seljuk Turks moved into Anatolia. This land was part of the Byzantine Empire. The Seljuks built a new state called the Sultanate of Rum. 
The sultanate grew very strong and rich. They took control of many ports by the sea. They also built caravanserai for traders. These were special places where travelers could stay. 
But hard times came to the Seljuks. They had to fight during the Crusades. Later, the Mongols invaded the land. The Seljuks lost a big battle in 1243. This battle was at Köse Dağ. After this, the Mongols held much power. The sultanate soon split into small groups. One of these groups was the Ottoman dynasty. 
The Sultanate of Rum was a strong Muslim state in Anatolia. This land is where the modern country of Turkey sits today. The people who ruled were the Seljuk Turks. They used the name "Rum" for their land. This name actually meant Roman. They used it because they lived on lands once held by the Roman and Byzantine Empires. 
The sultanate grew by taking over new lands and building trade paths. They built special buildings called caravanserai. These were safe places for traders to stay while traveling. This system helped goods move from Iran and Central Asia through Anatolia. 
History shows that the sultanate began in the year 1077. A leader named Suleiman ibn Qutalmish started it. He was a cousin of a famous ruler named Alp Arslan. At first, the capital was the city of Nicaea. Later, the capital moved to a city called Iconium. Suleiman's son, Kilij Arslan I, also ruled the land. He had to defend the state against the First Crusade. The sultanate saw many different leaders over the centuries.
The sultanate reached its highest power in the late 12th and early 13th centuries. Leaders like Kaykhusraw I and Kayqubad I made the state very large. They captured important ports on the Mediterranean and Black Sea coasts. 
Hard times arrived when the Mongols invaded the land. In 1243, the Seljuks fought the Battle of Köse Dağ. They lost this big battle to the Mongol forces. 
The Sultanate of Rum was a Sunni Muslim state located in Anatolia. This region is where the modern nation of Turkey exists today. The state was established by the Seljuk Turks following the Battle of Manzikert in 1071. The name "Rum" was a synonym for the medieval Roman Empire. It is derived from Aramaic and Parthian names for ancient Rome. The Seljuk Turks used this name to refer to the Anatolian territories. This sultanate is considered the beginning of Turkish history in Anatolia. 
The establishment of the state followed years of migration. Since the 1030s, Turkish groups moved into Anatolia seeking pastureland. This movement penetrated the borders of the Byzantine Empire. In 1077, Suleiman ibn Qutalmish seceded from the larger Seljuk Empire. He was a distant cousin of the ruler Alp Arslan. Suleiman gained control of Byzantine cities like Nicaea between 1075 and 1081. He established a sultanate that was initially a Byzantine vassal state. Over several years, the state became increasingly independent.
Trade and economy played a vital role in the sultanate's development. The Seljuks developed a system of caravanserai to move goods. A caravanserai is a roadside inn for travelers and merchants. This system connected trade routes from Iran and Central Asia through Anatolia. The sultanate also formed strong trade ties with the Genoese. This economic activity created significant wealth for the state. This wealth allowed the sultans to absorb other Turkish states. These included the Danishmendids, the House of Mengüjek, the Saltukids, and the Artuqids. 
The sultanate faced many military challenges, including the Crusades. Kilij Arslan I was the first Muslim commander against the Crusades. He defeated the People's Crusade in 1096 but lost to the First Crusade. This forced him to move his capital to Konya in south-central Anatolia. Later, the Second Crusade brought European kings into the conflict. These kings were Louis VII of France and Conrad III of Germany. Both armies were defeated by the Seljuk Turks after crossing Anatolia. During the late 12th century, Kilij Arslan II also defeated a Byzantine army. This victory happened at the Battle of Myriokephalon in 1176. 
Seljuk power reached its highest point during the late 12th and early 13th centuries. This period is known as the sultanate's apogee. Leaders like Kaykhusraw I and Ala Al-Din Kayqubad I expanded the borders. Kaykhusraw I captured the harbor of Attalia in 1207. Kaykaus I captured Sinop and made the Empire of Trebizond a vassal in 1214. Kayqubad I acquired more Mediterranean lands between 1221 and 1225. He even sent forces across the Black Sea to Crimea. The sultanate controlled key ports on both the Mediterranean and Black Sea coasts. 
Internal and external pressures eventually weakened the state. In 1239, Kaykhusraw II faced a popular uprising led by Baba Ishak. This revolt lasted three years and weakened the sultanate's army. Shortly after, the expanding Mongol Empire became a major threat. The Mongols took Erzurum in 1242. In 1243, the Seljuks were crushed at the Battle of Köse Dağ. This battle took place between the cities of Sivas and Erzincan. After this defeat, the Seljuk Turks became vassals of the Ilkhanate. The sultanate was divided among the sons of Kaykhusraw II for a time. 
The decline of the sultanate led to a new era in Anatolia. For the rest of the 13th century, the Seljuks acted as vassals. The last vassal sultan, Mesud II, was murdered in 1308. The dissolution of the state left behind many small Turkish principalities. These were called beyliks. Among these small states was the Ottoman dynasty. The Ottomans eventually conquered the remaining lands. They reunited Anatolia to form the Ottoman Empire.
