Military campaigns - Western Xia Dynasty
During the 1206 political rise of Genghis Khan, the Mongol Empire created by Genghis Khan and his allies was neighboured to the west by the Tanguts' Western Xia Dynasty. To its east and south was the Jin Dynasty, founded by the Manchurian Jurchens, who ruled northern China as well as being the traditional overlord of the Mongolian tribes for centuries.
Genghis Khan organized his people, army, and his state to first prepare for war with Western Xia, or Xi Xia, which was closer to the Mongolian lands. He correctly believed that the more powerful Jin Dynasty's young ruler would not come to the aid of Xi Xia. When the Tanguts requested help from the Jin Dynasty, they were flatly refused. Despite initial difficulties in capturing its well-defended cities, Genghis Khan forced the surrender of Western Xia by 1209.

Jin Dynasty
In 1211, after the conquest of Western Xia, Genghis Khan planned again to conquer the Jin Dynasty. The commander of the Jin Dynasty army made a tactical mistake in not attacking the Mongols at the first opportunity. Instead, the Jin commander sent a messenger, Ming-Tan, to the Mongol side, who promptly defected and told the Mongols that the Jin army was waiting on the other side of the pass. At this engagement fought at Badger Pass the Mongols massacred thousands of Jin troops. In 1215 Genghis besieged, captured, and sacked the Jin capital of Yanjing (later known as Beijing). This forced the Emperor Xuanzong to move his capital south to Kaifeng, abandoning the northern half of his kingdom to the Mongols.

Kara-Khitan Khanate
Kuchlug, the deposed Khan of the Naiman confederation that Temüjin defeated and folded into the Mongol nation, fled west and usurped the khanate of Kara-Khitan (also known as Kara Kitay). Genghis Khan decided to conquer the Kara-Khitan khanate and defeat Kuchlug, possibly to take him out of power. By this time the Mongol army was exhausted from ten years of continuous campaigning in China against the Western Xia and Jin Dynasty. Therefore Genghis sent only two tumen (20,000 soldiers) against Kuchlug, under his younger general, Jebe, known as "The Arrow".
With such a small force, the invading Mongols were forced to change strategies and resort to inciting internal revolt among Kuchlug's supporters, leaving the Khara-Khitan khanate more vulnerable to Mongol conquest. As a result, Kuchlug's army was defeated west of Kashgar. Kuchlug fled again, but was soon hunted down by Jebe's army and executed. By 1218, as a result of defeat of Kara-Khitan khanate, the Mongol Empire and its control extended as far west as Lake Balkhash, which bordered the Khwarezmia (Khwarezmid Empire), a Muslim state that reached the Caspian Sea to the west and Persian Gulf and the Arabian Sea to the south.

Khwarezmian Empire
n the early 1200s, the Khwarezmian Dynasty was governed by Shah Ala ad-Din Muhammad. Genghis Khan saw the potential advantage in Khwarezmia as a commercial trading partner, and, instead of sending an invasion force, he initially sent a 500-man caravan to establish trade ties with the empire. However, Inalchuq, the governor of the Khwarezmian city of Otrar, attacked the caravan that came from Mongolia, claiming that the caravan was a conspiracy against Khwarezmia. The situation became more complicated as the governor later refused to make repayments for the looting of the caravan and handing over the perpetrators. Genghis Khan then sent again a second group of three ambassadors (two Mongols and a Muslim) to meet the Shah himself. The Shah had all the men shaved and the Muslim beheaded and sent his head back with rest of the two ambassadors. This was seen as an affront and insult to Genghis Khan. Outraged Genghis Khan planned one of his largest invasion campaigns by organizing together around 200,000 soldiers (20 tumens), his most capable generals and some of his sons.
The Mongol army under command of Genghis Khan, generals and sons crossed the Tien Shan mountains by entering the area controlled by the Khwarezmian Empire. After compiling intelligence from many sources Genghis Khan carefully prepared his army, which was divided into three groups. His son Jochi led the first division into the northeast of Khwarezmia. The second division under Jebe marched secretly to the southeast part of Khwarzemia to form, with the first division, a pincer attack on Samarkand. The third division under Genghis Khan and Tolui marched to the northwest and attacked Khwarzemia from that direction.
The Shah's army was split by diverse internal disquisitions and by the Shah's decision to divide his army into small groups concentrated in various cities. This fragmentation was decisive in Khwarezmia's defeats, as it allowed the Mongols, although exhausted from the long journey, to immediately set about defeating small fractions of the Khwarzemi forces instead of facing a unified defense. The Mongol army quickly seized the town of Otrar, relying on superior strategy and tactics. Genghis Khan ordered the execution of many of the inhabitants and executed Inalchuq by pouring molten silver into his ears and eyes, as retribution for his actions. Near the end of the battle the Shah fled rather than surrender. Genghis Khan charged Subutai and Jebe with hunting him down, giving them two years and 20,000 men. The Shah died under mysterious circumstances on a small island within his empire.
The Mongols' conquest, even by their own standards, was brutal. After the capital Samarkand fell, the capital was moved to Bukhara by the remaining men, and Genghis Khan dedicated two of his generals and their forces to completely destroying the remnants of the Khwarezmid Empire, including not only royal buildings, but entire towns and even vast swaths of farmland. According to stories, Genghis Khan even went so far as to divert a river through the Khwarezmid emperor's birthplace, erasing it from the map.
The heir Shah Jalal Al-Din, who was supported by a nearby town, battled the Mongols several times with his father's armies. However, internal disputes once again split his forces apart, and they were forced to flee Bukhara after yet another devastating defeat, effectively bringing the Khwarezmid Empire to an end.
In the meantime, Genghis Khan selected his third son Ögedei as his successor before his army set out, and specified that subsequent Khans should be his direct descendants. Genghis Khan also left Muqali, one of his most trusted generals, as the supreme commander of all Mongol forces in Jin China while he was out battling the Khwarezmid Empire to the west.

Georgia and Volga Bulgaria
After the complete defeat of the Khwarezmian Empire in 1220, Genghis Khan gathered his forces in Persia and Armenia to return to the Mongolian steppes. Under the suggestion of Subutai, the Mongol army was split into two component forces. Genghis Khan led the main army on a raid through Afghanistan and northern India towards Mongolia, while another 20,000 (two tumen) contingent marched through the Caucasus and into Russia under generals Jebe and Subutai. They pushed deep into Armenia and Azerbaijan. The Mongols destroyed Georgia, sacked the Genoese trade-fortress of Caffa in Crimea and overwintered near the Black Sea. Heading home, Subutai's forces attacked the Kipchaks and were intercepted by the allied but poorly coordinated troops of Mstislav the Bold of Halych and Mstislav III of Kiev, along with about 80,000 Kievan Rus' troops to stop their actions. Subutai sent emissaries to the Slavic princes calling for a separate peace, but the emissaries were executed. At the Battle of Kalka River in 1223, Subutai's forces defeated the larger Kievan force, while losing the battle of Samara Bend against the neighboring Volga Bulgars.
The Mongols learned from captives of the abundant green pastures beyond the Bulgar territory, allowing for the planning for conquest of Hungary and Europe. The Russian princes then sued for peace. Subutai agreed but was in no mood to pardon the princes. As was customary in Mongol society for nobility, the Russian princes were given a bloodless death. Subutai had a large wooden platform constructed on which he ate his meals along with his other generals. Six Russian princes, including Mstislav III of Kiev, were put under this platform and crushed to death.
Genghis Khan recalled Subutai back to Mongolia soon afterwards, and Jebe died on the road back to Samarkand. Subutai and Jebe's famous cavalry expedition, in which they encircled the entire Caspian Sea defeating all armies in their path, except for that of the Volga Bulgars, remains unparalleled to this day, and word of the Mongol triumphs began to trickle to other nations, particularly Europe.
These two campaigns are generally regarded as reconnaissance campaigns that tried to get the feel of the political and cultural elements of the regions. In 1225 both divisions returned to Mongolia. These invasions ultimately added Transoxiana and Persia to an already formidable empire while destroying any resistance along the way.
Under Genghis Khan's grandson Batu and the Golden Horde, the Mongols returned to definitively conquer Volga Bulgaria and the Kievan Rus in 1237, concluding the campaign in 1240.

Western Xia and Jin Dynasty
The vassal emperor of the Tanguts (Western Xia) had refused to take part in the war against the Khwarezmid Empire after Genghis Khan and the main army marched towards Kharezmian Empire. Plus Western Xia and the defeated Jin Dynasty formed a coalition to resist the Mongols, counting on the campaign against the Khwarezmians to drain the Mongols' ability to respond effectively. Their cause was further emboldened by the Khan's expeditions further west, which had drawn the bulk of his army off into prolonged campaigns in Persia and Eastern Europe.
In 1226, immediately after returning from the west, Genghis Khan began a retaliatory attack on the Tanguts. His armies quickly took Heisui, Ganzhou and Suzhou (not the Suzhou in Jiangsu province), and in the autumn he took Xiliang-fu. One of the Tangut generals challenged the Mongols to a battle near Helanshan, but was soundly defeated. In November, Genghis laid siege to the Tangut city Lingzhou, and crossed the Yellow River, defeating the Tangut relief army. According to legend, it was here that Genghis Khan reportedly saw a line of five stars arranged in the sky, and interpreted it as an omen of his victory.
In 1227, Genghis Khan's army attacked and destroyed the Tangut capital of Ning Hia, and continued to advance, seizing Lintiao-fu, Xining province, Xindu-fu, and Deshun province in quick succession in the Spring. At Deshun, the Tangut general Ma Jianlong put up a fierce resistance for several days and personally led charges against the invaders outside the city gate. Ma Jianlong later died from wounds received from arrows in battle. Genghis Khan, after conquering Deshun, went to Liupanshan (Qingshui County, Gansu Province) to escape the severe summer. The new Tangut emperor quickly surrendered to the Mongols, and the rest of the Tanguts officially surrendered soon after. Not happy with their betrayal and resistance, Genghis Khan ordered the entire imperial family to be executed, effectively ending the Tangut lineage.
