Context paragraphs:
1929–30 British Home Championship: The 1929-30 British Home Championship was an edition of the annual international football tournament played between the British Home Nations.  1930 was the year in which the tournament finally gained a serious rival as the premier international football competition, with the inception of the 1930 FIFA World Cup, held in Uruguay.  The Home Nations were not however members of FIFA due to disputes over the growing professionalism in continental and South American football.  As a result, they were not able to attend and indicated that even if they were invited they would have no interest in attending, deeming foreign opposition too weak for serious contest.  It is interesting to speculate what would have happened had the Home Nations entered the tournament, especially as the tide of world football was changing against Britain.  The England team, which dominated the 1930 championship, had lost to Spain the year before in the first defeat by a foreign football team, and in the same year they only managed draws with Germany and Austria.  The Scottish side, which had won most of the previous ten championships, was likewise unprepared, only playing its first game outside the British Isles in 1929, and being heavily defeated on tour in 1931 by both the Austrians and the Italians.

1883–84 British Home Championship: The 1883–84 British Home Championship was the inaugural international football tournament, played between the Home Nations of the British Isles which at the time made up the constituent nations of the United Kingdom; England, Scotland, Wales and Ireland.  International football matches had begun with annual games played between England and Scotland in 1872 and they had been joined by Wales in 1876 and Ireland in 1882.  In 1883 the four governing bodies held a conference to standardise the rules of the game and to arrange a tournament to be held yearly in which the four nations would all play each other once in a league format.  This championship would be considered by many to be the world's premier international football tournament for the next 46 years.
