There was a remarkable power shift in international politics from the end of the 19th century to the first half of the 20th century. The rising states in different regions—Japan in East Asia, the Unites States in the Americas, and Germany in Europe—began to displace in various ways British hegemony worldwide. Following the basic logic of the power transition theory, the world at the time was in an unstable condition in which Japan, the United States, and Germany, as a dissatisfied and non-status quo rising power, sought to change the existing international and especially regional order.
The purpose of this paper, which focuses on Japan and the United States as emerging powers in this era, is to make it clear how the orders of two regions, East Asia and the Americas, although geographically separated, evolved by interacting with each other through the Monroe Doctrine’s functions.
The Monroe Doctrine was originally pronounced in 1823 by U.S. President James Monroe, who declared the principle of mutual non-intervention between the Americas and Europe, eventually becoming a longstanding tenet of U.S. foreign policy. In particular, around the turn of the century, the doctrine, by functioning as an ideational mechanism that legitimized American leadership in the Americas, contributed to a “peaceful” power or hegemonic transition in the region between Great Britain and the U.S. On the other hand, this American doctrine was applied beyond the Asia-Pacific to East Asia, as an idea that could sanction Japanese domination over the region symbolized by the proposal of a “Japanese” Monroe Doctrine by President Theodore Roosevelt in 1905. However, the efforts of seeking the Japanese Monroe Doctrine ultimately resulted in the failure of a peaceful power transition in East Asia, despite or because of the use of the Monroe Doctrine.
There are a number of preceding studies, mostly using a historical approach, on the Monroe Doctrine. Nevertheless, few studies explore the synchronic developments of the Monroe Doctrine and the Japanese Monroe Doctrine, which interconnected the regional order already in process in East Asia and the Americas,from the viewpoint conceptualizing the doctrines as ideas of legitimizing regional hegemony. Furthermore, this paper, highlighting the workings of an ideational factor, the (Japanese) Monroe Doctrine, in the rise of Japan and the rise of the United States, provides a perspective different from the traditional power transition theory that focuses on material power. It can also be said that revisiting the past of the Japanese Monroe Doctrine offers an implication for contemporary international politics in East Asia, which face a new power shift and the possibility of a “Chinese” Monroe Doctrine.
This paper examines (1) the rise of the U.S. and the Monroe Doctrine in the Americas from the late 19th century to the early 20th century; (2) the rise of Japan and the Japanese Monroe Doctrine in East Asia from 1900 to the 1910s; and (3) the development of the Monroe Doctrine and the Japanese Monroe Doctrine in the Americas and East Asia from the 1920s to the 1930s.
