local rulers throughout this period, and development remained limited to Dili. Coffee production continued to expand, becoming especially prominent in the north coast near Dili, such as in Liquiçá, Motael, and Hatulia. Conflicts with the Dutch continued throughout this period, entwined with shifting loyalties of local rulers. This led to three treaties being signed to define the border, in 1851, 1854, and 1859. Through these, Portugal ceded its remaining territory and claims on Flores and the Solor islands, while the Netherlands ceded Maubara and Citrana to Portugal, and dropped its claim on Atauro. The 1851 treaty which included these territorial arrangements was initiated by Portuguese Governor , who sought negotiations with officials in Kupang and Batavia shortly after his arrival to Timor in 1851. This was done without consulting authorities in Portugal, who upon hearing about the deal thought it too favourable to the Dutch. Lisbon revoked Timor's autonomy, and Lopes de Lima fled to Batavia rather than return to Portugal. The 1854 border treaty was rejected by the Dutch House of Representatives, who felt it did not protect religious liberty. The final 1859 Treaty of Lisbon stood in place until 1913, when the Portuguese and Dutch formally agreed to split the island between them. The definitive border was established by the Permanent Court of Arbitration in 1914 and ratified in 1916; it remains the international boundary between East Timor and Indonesia. The 1859 border treaty was not implemented all at once, with local transfers out of sync with the official ratification in August 1860. Rebellions against Portuguese rule broke out to the east and west of Dili in 1861. This revolt saw forces from Laclo and Ulmera lay siege to Dili. The Portuguese sought assistance from other kingdoms, and managed to suppress the revolt. Further military battles occurred over succeeding years, until 1888 when the thirteen kingdoms of the island's east swore fealty to Portugal. This did not however secure Portuguese control over the whole territory, as kingdoms in other areas remained effectively autonomous. Coffee soon became the territory's primary export, to the point where some sandalwood forest recovered. There was a small renaissance in the sandalwood trade in the 1850s, including wood smuggled across the border in order to obtain valuable Dutch currency. This collapsed in the 1860s, as new sources elsewhere depressed prices. Then Governor shifted the focus of exports to coffee. Efforts began to regrow sandalwood
