Answer:
He chose Ogodei
Explanation:
When Genghis Khan was deciding who should succeed him, he had trouble choosing between his four sons. Tolui had a strong reputation for his military skills, and was very successful as a general, but Genghis Khan chose Ögodei, who was more capable politically. Genghis Khan felt that Tolui would be too cautious to be an effective leader. Tolui was with his father on campaign against Xi Xia in 1227.[citation needed]
