During the beginning of the First World War, when the economic ideologies of the world changed from a focus on free-trade to a planned economy, the ideas of John Maynard Keynes thrived. He shaped the mindset of the British government, as well as many other countries' at that time, and also helped them create their war-time economies. Keynes was a strong believer of government intervention and that is what he encouraged. Countries began to spend against the wind; spending money during bad times and saving money during good times. This kind of government stimulation also meant that they would provide subsidies to companies in need of financial help. Therefore, through his strong economic theories, John Maynard Keynes was able to influence the political actions of the governments during the beginning of the twentieth century.
