Nevertheless, early political, economic and cultural advances gave Catalonia ""a mode of organization and an awareness of its own identity which might in some ways be described as national, though the idea of popular or national sovereignty did not yet exist"" (Balcells 9). Other scholars like Kenneth McRoberts and Katheryn Woolard hold similar views. Both support Pierre Vilar, who contends that in 13th and 14th centuries "the Catalan principality was perhaps the European country to which it would be the least inexact or risky to use such seemingly anachronistic terms as political and economic imperialism or 'nation-state'" (McRoberts 13). In other words, an array of political and cultural forces laid the foundations of Catalan "national" identity.
