evidence: Well, the Treaty of Zamora established a border of a thousand and a quarter kilometers that, with slight situational variations, remained more or less stable over the centuries. The cases of the aforementioned Olivenza (occupied by Spain in 1801 during the War of the Oranges), Táliga (a parish of the former that also remained in Spanish hands), and the Coto Mixto (a territory formed by the villages of Rubiás, Meaus, Santiago, and Montealegre) were exceptions. With these exceptions (not all, because the Coto Mixto would be abolished), the final borders were agreed upon in the Treaty of Lisbon of 1864, negotiated by the delegates of Queen Isabella II of Spain and King Luís I of Portugal, coming into effect in 1868. However, in 1926, the Border Agreement was signed in Lisbon, granting the inhabitants of the border areas the same benefits as those of the other territories specified in the previous treaty. [...] In the Portuguese administration, it is the freguesia (part of a concelho or municipality, in this case, that of Bragança) of Rio de Onor, named after the river that runs through it (Fontano in Spanish). The truth is that this is its real name, the historical one, and, in fact, it appears in Spanish censuses as Rionor; both the interspersed "h" and the "de Castilla" complement were added in the Franco era to Castilianize it.
