Tonga

History
As OTL until 1828, except the arrival of the British missionaries.

In July 1829, a small voyage of Montenegrins, led by Sovereign Prince Daniel I of Montenegro, arrived in Nuku'alofa, the royal seat of the Tongan Empire. Unlike the other places where he visited, such as Mozambique, where the Montenegrins have settled their first colony, Tonga welcomed him dearly. Daniel became a national guest and enjoyed his stay. Therefore, Daniel offered protection to the Tongans, who quickly agreed. During his stay in Tonga, Daniel and his associates conducted extensive researches on the realms of Tonga, including the people, language, culture and natural resources. Eventually, Daniel left seven out of the eighteen ships in Tonga and proceeded with his journey in December.

While Daniel was away, the head of the Montenegrin fleet in Tonga, Anders Bakic, attempted to develop Tonga into a cohabiting colony. Aleamotu'a was baptised as Wolfgang, and received the surname Tonga-Tupou from a Montenegrin Lutheran priest. Lutheranism spread rapidly across the islands. The ships brought with them many crops that the Montenegrins gathered across the world: wheat, millet, barley, oat, soybean, pea, bean, lentil, squash, corn, coffee and cocoa. Tongans received these crops and multiplied them in numbers, creating a diverse agricultural landscape that ensured an advantage compared to other Polynesian peoples. The same Montenegrin ships introduced iron and steel from other lands in trade to Tonga, and eventually ten new steel ships were built by the Montenegrins and Tongans. At least six were then commissioned to the Tongan Navy, which still includes mostly wooden canoes. Wolfgang then led his navy to invade the surrounding islands, restoring the former Tongan Empire. By 1845, at his death, Tonga has already conquered the Samoas, Niue, OTL Wallis and Futuna, Fiji, Tokelau, the Cook Islands and parts of Tuvalu and Vanuatu.

In 1840, coal and the steam engine was introduced by the Montenegrins into Tonga. The Tongans learnt how to build and operate those engines, which solved the problem of overpopulation that has been driving excessive urbanisation up to that point.
