The term "British subject" has several different meanings depending on the time period. Before 1949, it referred to almost all subjects of the British Empire (including the United Kingdom, Dominions, and colonies, but excluding protectorates and protected states). Between 1949 and 1983, the term was synonymous with Commonwealth citizen. Currently, it refers to people possessing a class of British nationality largely granted under limited circumstances to those connected with Ireland or British India born before 1949. Individuals with this nationality are British nationals and Commonwealth citizens, but not British citizens. The status under the current definition does not automatically grant the holder right of abode in the United Kingdom but most British subjects do have this entitlement. About 32,400 British subjects hold active British passports with this status and enjoy consular protection when travelling abroad; fewer than 800 do not have right of abode in the UK. Nationals of this class without right of abode are subject to immigration controls when entering the UK. If they hold no other citizenship, British subjects without right of abode in the UK are effectively stateless, as they are not guaranteed the right to enter the country in which they are nationals. History of British nationality law#Early English and British nationality law and History of citizenship#Great Britain Before the concept of nationality was codified in legislation, inhabitants of English communities owed allegiance to their feudal lords, who were themselves vassals of the monarch. This system of loyalty, indirectly owed to the monarch personally, developed into a general establishment of subjecthood to the Crown. Calvin's Case in 1608 established the principle of jus soli, that all those who were born within Crown dominions were natural-born subjects. After the Acts of Union 1707, English and Scottish subjects became British subjects. Natural-born subjects were considered to owe perpetual allegiance to the Crown, and could not voluntarily renounce British subject status until 1870, when it was first permitted.
