Attila is not the correct answer for this question. The correct answer is Genghis Khan himself. Genghis Khan was the founder and leader of the Mongol Empire, which eventually became the largest contiguous empire in history. He was able to unite various Mongol and Turkish tribes under his leadership, forming a powerful confederation.

Here is a detailed explanation of how Genghis Khan stitched together the size of his confederation:

Formation of the Mongol Empire:
1. Rise to Power: Genghis Khan, originally named Temujin, was born into a nomadic Mongol tribe in the 12th century. He gradually gained power and influence through strategic alliances, military victories, and his exceptional leadership skills.

2. Uniting the Mongols: Genghis Khan began by consolidating the Mongol tribes, ending their internal conflicts, and bringing them under his rule. He implemented a code of laws (Yassa) to govern his subjects and foster loyalty.

3. Expansion into Central Asia: Once he had established control over the Mongols, Genghis Khan turned his attention towards neighboring Turkic tribes. Through a combination of military conquests and strategic marriages, he forged alliances with these tribes, incorporating them into his confederation.

4. Military Tactics: Genghis Khan revolutionized warfare by introducing innovative military tactics. He organized his armies into decimal units, with each unit consisting of ten soldiers. This structure allowed for better coordination and flexibility on the battlefield. He also emphasized skilled horsemanship and archery.

5. Diplomacy and Trade: Genghis Khan recognized the importance of diplomacy and trade in strengthening his confederation. He established diplomatic relations with neighboring kingdoms and actively promoted trade along the Silk Road, facilitating cultural exchange and economic growth.

6. Conquest of Northern China: Genghis Khan's confederation then turned its attention towards the Jin Dynasty in northern China. Through a series of military campaigns, they successfully conquered the region, expanding their territory and resources.

7. Expansion into Central Europe: After consolidating their control over China, Genghis Khan's successors, particularly his grandson Batu Khan, led further military campaigns westward. They conquered vast territories in Central Asia and Eastern Europe, including parts of Russia, Hungary, and Poland.

Conclusion:
Genghis Khan played a central role in stitching together the confederation of Mongol and Turkish tribes. Through his military prowess, diplomacy, and innovative tactics, he was able to unite these tribes and create the Mongol Empire, which stretched across a vast expanse of land. His leadership and vision enabled the empire to flourish and leave a lasting impact on world history.
