Until August 1914 a sensible, law-abiding Englishman could pass through life and hardly notice the existence of the state, beyond the post office and the policeman. He could live where he liked and as he liked. He had no official number or identity card. He could travel abroad or leave his country for ever without a passport or any sort of official permission. He could exchange his money for any other currency without restriction or limit. He could buy goods from any country in the world on the same terms as he bought goods at home. For that matter, a foreigner could spend his life in this country without permit and without informing the police. Unlike the countries of the European continent, the state did not require its citizens to perform military service. An Englishman could enlist, if he chose, in the regular army, the navy, or the territorials. He could also ignore, if he chose, the demands of national defence. Substantial householders were occasionally called on for jury service. Otherwise, only those helped the state who wished to do so.
The Englishman paid taxes on a modest scale: nearly £200 million in 1913-14, or rather less than 8 per cent. of the national income. The state intervened to prevent the citizen from eating adulterated food or contracting certain infectious diseases. It imposed safety rules in factories, and prevented women, and adult males in some industries, from working excessive hours. The state saw to it that children received education up to the age of 13. Since 1 January 1909, it provided a meagre pension for the needy over the age of 70. Since 1911, it helped to insure certain classes of workers against sickness and unemployment. This tendency towards more state action was increasing. Expenditure on the social services had roughly doubled since the Liberals took office in 1905. Still, broadly speaking, the state acted only to help those who could not help themselves. It left the adult citizen alone.
All this was changed by the impact of the Great War. The mass of the people became, for the first time, active citizens. Their lives were shaped by orders from above; they were required to serve the state instead of pursuing exclusively their own affairs. Five million men entered the armed forces, many of them (though a minority) under compulsion. The Englishman’s food was limited, and its quality changed, by government order. His freedom of movement was restricted; his conditions of work prescribed. Some industries were reduced or closed, others artificially fostered. The publication of news was fettered. Street lights were dimmed. The sacred freedom of drinking was tampered with: licensed hours were cut down, and the beer watered by order. The very time on the clocks was changed. From 1916 onwards, every Englishman got up an hour earlier in summer than he would otherwise have done, thanks to an act of parliament. The state established a hold over it citizens which, though relaxed in peacetime, was never to be removed and which the second World war was again to increase. The history of the English state and of the English people merged for the first time.
