Treason is the crime of attacking a state authority to which one owes allegiance. This typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying on its military, its diplomats, or its secret services for a hostile and foreign power, or attempting to kill its head of state. A person who commits treason is known in law as a traitor.
The War Measures Act was a statute of the Parliament of Canada that provided for the declaration of war, invasion, or insurrection, and the types of emergency measures that could thereby be taken. The Act was brought into force three times in Canadian history: during the First World War, Second World War, and the 1970 October Crisis.
Defence Regulation 18B, often referred to as simply 18B, was one of the Defence Regulations used by the British Government during and before the Second World War. The complete name for the rule was Regulation 18B of the Defence (General) Regulations 1939. It allowed the internment without trial of people suspected of being actively opposed to the ongoing war with Germany during World War II such as separatist elements or were otherwise suspected of ideological Nazi-aligned sympathy. The effect of 18B was to suspend the right of affected individuals to habeas corpus.
The Treachery Act 1940 was an Act of the Parliament of the United Kingdom effective during World War II to facilitate the prosecution and execution of enemy spies, suspended afterwards, and repealed in 1968 or 1973, territory depending.

The Emergency Powers (Defence) Act 1939 was emergency legislation passed just prior to the outbreak of World War II by the Parliament of the United Kingdom to enable the British government to take up emergency powers to prosecute the war effectively. It contained clauses giving the government wide powers to create Defence Regulations by Order in Council. These regulations governed almost every aspect of everyday life in the country during the War. Two offences under the regulations were punishable with death. Following the conclusion of the war, the 1939 Act was repealed, with the individual regulations gradually following suit. As of 2023, at least one Regulation remains in force.
The Emergency Powers Act 1920 was an Act of the Parliament of the United Kingdom that gave the Sovereign power, in certain circumstances, to declare a state of emergency by proclamation. The Act also authorised emergency regulations to be issued by Order in Council.

The Articles of War are a set of regulations drawn up to govern the conduct of a country's military and naval forces. The first known usage of the phrase is in Robert Monro's 1637 work His expedition with the worthy Scot's regiment called Mac-keyes regiment etc. and can be used to refer to military law in general. In Swedish, the equivalent term Krigsartiklar, is first mentioned in 1556. However, the term is usually used more specifically and with the modern spelling and capitalisation to refer to the British regulations drawn up in the wake of the Glorious Revolution and the United States regulations later based on them.
The Defence of India Act 1915, also referred to as the Defence of India Regulations Act, was an emergency criminal law enacted by the Governor-General of India in 1915 with the intention of curtailing the nationalist and revolutionary activities during and in the aftermath of the First World War. It was similar to the British Defence of the Realm Acts, and granted the Executive very wide powers of preventive detention, internment without trial, restriction of writing, speech, and of movement. However, unlike the English law which was limited to persons of hostile associations or origin, the Defence of India act could be applied to any subject of the King, and was used to an overwhelming extent against Indians. The passage of the act was supported unanimously by the non-official Indian members in the Viceroy's legislative council, and was seen as necessary to protect against British India from subversive nationalist violence. The act was first applied during the First Lahore Conspiracy trial in the aftermath of the failed Ghadar Conspiracy of 1915, and was instrumental in crushing the Ghadr movement in Punjab and the Anushilan Samiti in Bengal. However its widespread and indiscriminate use in stifling genuine political discourse made it deeply unpopular, and became increasingly reviled within India. The extension of the law in the form of the Rowlatt Act after the end of World War I was opposed unanimously by the non-official Indian members of the Viceroy's council. It became a flashpoint of political discontent and nationalist agitation, culminating in the Rowlatt Satyagraha. The act was re-enacted during World War II as Defence of India act 1939. Independent India retained the law in a number of amended forms, which have seen use in proclaimed states of national emergency including Sino-Indian War, Bangladesh crisis, The Emergency of 1975 and subsequently the Punjab insurgency.
The Official Secrets Act 1920 was an Act of the Parliament of the United Kingdom.
The King's Regulations is a collection of orders and regulations in force in the Royal Navy, British Army, Royal Air Force, and Commonwealth Realm Forces, forming guidance for officers of these armed services in all matters of discipline and personal conduct. Originally, a single set of regulations were published in one volume. By the mid 19th century, there were separate editions of the Queen's Regulations for the Navy and the Army, and there is now one for each of the United Kingdom's armed forces.
The Ministry of Defence Police (MDP) in the United Kingdom can trace its origins back to 1686, and has gone through a number of evolutions over the centuries to achieve its present-day form. Until late 1965, the Royal Navy, British Army and Royal Air Force were controlled by separate departments: the Board of Admiralty, the Army Board and the Air Ministry respectively, each had its own Cabinet Minister. In that year it was decided that the three services should be placed under the control of one Minister of State for Defence, and the present Ministry of Defence was formed.
Head of the Armed Forces is the position of the sovereign of the United Kingdom as commander-in-chief of the British Armed Forces. Supreme military authority vests in the monarch and extends to the exercise of several personal prerogatives. However, routine administration of the military is delegated as a matter of law to the Defence Council of the United Kingdom, a body officially charged with the direction and command of the Armed Forces. As the Defence Council and its service boards are all a part of the Ministry of Defence, which itself is a ministerial department of the Government of the United Kingdom, the prime minister makes the key decisions on the use of the Armed Forces, while the secretary of state for defence assists the prime minister in the development of defence policy and administers the day-to-day military operations.
The Incitement to Disaffection Act (Ireland) 1797 was an act of the Parliament of the Kingdom of Ireland. It made equivalent provision to the Incitement to Mutiny Act 1797 for Ireland.
Farey v Burvett is an early High Court of Australia case concerning the extent of the defence power of the Commonwealth. The majority of the Court took an expansive view of the defence power in a time of war, holding that the defence power extended to fixing the maximum price for bread. The Court adopted a different approach to the interpretation of the defence power which emphasised the purpose of the legislation, the defence of Australia, rather than the subject matter. As the law fell within a Commonwealth power, whether the law was necessary or appropriate for the defence of Australia was a matter for Parliament.
