How did Taufa'ahau help end Tonga's period of war and disorder?

Between 1799 and 1852, Tonga experienced a period of significant war and disorder. Taufa‘ahau helped end this instability through his conversion to Christianity by Methodist missionaries in 1831, which facilitated the rapid spread of the religion across the islands.1

By embracing Christianity and adopting missionary-designed codes of law, Taufa‘ahau was able to consolidate his power and address the lawlessness caused by European traders and beachcombers. He assumed the title of Tu‘i Kanokupolu and became King George Tupou I in 1845. During his long reign, he unified the country and established a modern administrative structure, including a legal code and a constitution in 1875, effectively transforming Tonga into a unified and independent nation.21
