Romanesque architecture had become a pan-European style and manner of construction, affecting buildings in countries as far apart as Ireland and Croatia, and Sweden and Sicily. The same wide geographic area was then affected by the development of Gothic architecture, but the acceptance of the Gothic style and methods of construction differed from place to place, as did the expressions of Gothic taste. The proximity of some regions meant that modern country borders did not define divisions of style. Many different factors like geographical/geological, economic, social, or political situations caused the regional differences in the great abbey churches and cathedrals of the Romanesque period that would often become even more apparent in the Gothic. For example, studies of the population statistics reveals disparities such as the multitude of churches, abbeys, and cathedrals in northern France while in more urbanised regions construction activity of a similar scale was reserved to a few important cities. Such an example comes from Roberto López, wherein the French city of Amiens was able to fund its architectural projects whereas Cologne could not because of the economic inequality of the two. This wealth, concentrated in rich monasteries and noble families, would eventually spread certain Italian, Catalan, and Hanseatic bankers. This would be amended when the economic hardships of the 13th century were no longer felt, allowing Normandy, Tuscany, Flanders, and the southern Rhineland to enter into competition with France.
