A protectorate, in its inception adopted by modern international law, is a dependent territory that has been granted local autonomy and some independence while still retaining the suzerainty of a greater sovereign state. In exchange for this, the protectorate usually accepts specified obligations, which may vary greatly, depending on the real nature of their relationship. Therefore, a protectorate remains an autonomous part of a sovereign state. They are different from colonies as they have local rulers and people ruling over the territory and experience rare cases of immigration of settlers from the country it has suzerainty of. However, a state which remains under the protection of another state but still retains independence is known as a protected state and is different from protectorates.
In amical protection, the terms are often very favorable for the protectorate. The political interest of the protector is frequently moral (a matter of accepted moral obligation, prestige, ideology, internal popularity, dynastic, historical, or ethno-cultural ties) or countering a rival or enemy power (e.g., preventing the rival from obtaining or maintaining control of areas of strategic importance). This may involve a very weak protectorate surrendering control of its external relations; this, however, may not constitute any real sacrifice, as the protectorate may not have been able to have similar use of them without the protector's strength.
Amical protection was frequently extended by the great powers to other Christian (generally European) states and to smaller states that had no significant importance[ambiguous]. In the post-1815 period, non-Christian states (such as China's Qing dynasty) also provided amical protection towards other much weaker states.
In modern times, a form of amical protection can be seen as an important or defining feature of microstates. According to the definition proposed by Dumienski (2014): "microstates are modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints". Examples of microstates understood as modern protected states include Andorra, Bhutan,Liechtenstein, San Marino, Monaco, Niue, the Cook Islands, and Palau.
Conditions regarding protection are generally much less generous for areas of colonial protection. The protectorate was often reduced to a de facto condition similar to a colony, but using the pre-existing native state as an agent of indirect rule. Occasionally, a protectorate was established by or exercised by the other form of indirect rule: a chartered company, which becomes a de facto state in its European home state (but geographically overseas), allowed to be an independent country which has its own foreign policy and generally its own armed forces.
In fact, protectorates were declared despite not being duly entered into by the traditional states supposedly being protected, or only by a party of dubious authority in those states. Colonial protectors frequently decided to reshuffle several protectorates into a new, artificial unit without consulting the protectorates, a logic disrespectful of the theoretical duty of a protector to help maintain its protectorates' status and integrity. The Berlin agreement of February 26, 1885 allowed European colonial powers to establish protectorates in Black Africa (the last region to be divided among them) by diplomatic notification, even without actual possession on the ground. This aspect of history is referred to as the Scramble for Africa. A similar case is the formal use of such terms as colony and protectorate for an amalgamation, convenient only for the colonizer or protector, of adjacent territories over which it held (de facto) sway by protective or "raw" colonial logic.
In practice, a protectorate often has direct foreign relations only with the protecting power, so other states must deal with it by approaching the protector. Similarly, the protectorate rarely takes military action on its own, but relies on the protector for its defence. This is distinct from annexation, in that the protector has no formal power to control the internal affairs of the protectorate.
Protectorates differ from League of Nations mandates and their successors, United Nations Trust Territories, whose administration is supervised, in varying degrees, by the international community. A protectorate formally enters into the protection through a bilateral agreement with the protector, while international mandates are stewarded by the world community-representing body, with or without a de facto administering power.
Trumon Sultanate (1770?), Langkat Sultanate (26 October 1869), Deli Sultanate (22 August 1862), Asahan Sultanate (27 September 1865), Siak Sultanate (1 February 1858) and Indragiri Sultanate (1838?) in Sumatra
Jogjakarta Sultanate (13 February 1755), Mataram Empire and Surakarta Sunanate (26 February 1677), Duchy of Mangkunegara (24 February 1757) and Duchy of Paku Alaman (22 June 1812) in Java.
Saar Protectorate (1947-1956), not colonial or amical, but a former part of Germany that would by referendum return to it, in fact a re-edition of a former League of Nations mandate. Most French protectorates were colonial.
Present India: Arkat (Arcot/Carnatic) was 1692-1750 a French protectorate until 1763 independence recognized under British protectorate
Comoros 21 April 1886 French protectorate (Anjouan) until 25 July 1912 when annexed.
Present Djibouti was originally, since 24 June 1884, the Territory of Obock and Protectorate of Tadjoura (Territoires Français d'Obock, Tadjoura, Dankils et Somalis), a French protectorate recognized by Britain on 9 February 1888, renamed on 20 May 1896 as French Somaliland (Côte Française des Somalis).
Mauritania on 12 May 1903 French protectorate; within Mauritanian several traditional states:
Adrar emirate since 9 January 1909 French protectorate (before Spanish)
The Taganit confederation's emirate (founded by Idaw `Ish dynasty), since 1905 under French protectorate.
The legal regime of "protection" was the formal legal structure under which French colonial forces expanded in Africa between the 1830s and 1900. Almost every pre-existing state in the area later covered by French West Africa was placed under protectorate status at some point, although direct rule gradually replaced protectorate agreements. Formal ruling structures, or fictive recreations of them, were largely retained as the lowest level authority figure in the French Cercles, with leaders appointed and removed by French officials.
Wallis declared to be a French protectorate by King of Uvea and Captain Mallet, 4 November 1842. Officially in a treaty becomes a French protectorate, 5 April 1887.
Sigave and Alo on the islands of Futuna and Alofi signed a treaty establishing a French protectorate on 16 February 1888.
The German Empire used the word Schutzgebiet, literally protectorate, for all of its colonial possessions until they were lost during World War I, regardless of the actual level of government control. Cases involving indirect rule included:
Ethiopia: 2 May 1889 Treaty of Wuchale, in the Italian language version, stated that Ethiopia was to become an Italian protectorate, while the Ethiopian Amharic language version merely stated that the Emperor could, if he so chose, go through Italy to conduct foreign affairs. When the differences in the versions came to light, EmperorMenelik II abrogated first the article in question (XVII), and later the whole treaty. The event culminated in the First Italo-Ethiopian War, in which Ethiopia was victorious and defended her sovereignty in 1896.
Libya: on 15 October 1912 Italian protectorate declared over Cirenaica (Cyrenaica) until 17 May 1919.
