1400—the period in which the poem is thought to have been written—Wales experienced several raids at the hands of the English, who were attempting to colonise the area. The Gawain poet uses a North West Midlands dialect common on the Welsh–English border, potentially placing him in the midst of this conflict. Patricia Clare Ingham is credited with first viewing the poem through the lens of postcolonialism, and since then a great deal of dispute has emerged over the extent to which colonial differences play a role in the poem. Most critics agree that gender plays a role but differ about whether gender supports the colonial ideals or replaces them as English and Welsh cultures interact in the poem. A large amount of critical debate also surrounds the poem as it relates to the bi-cultural political landscape of the time. Some argue that Bertilak is an example of the hybrid Anglo-Welsh culture found on the Welsh–English border. They therefore view the poem as a reflection of a hybrid culture that plays strong cultures off one another to create a new set of cultural rules and traditions. Other scholars, however, argue that historically much Welsh blood was shed well into the 14th century, creating a situation far removed from the more friendly hybridisation suggested by Ingham. To support this argument further, it is suggested that the poem creates an "us versus them" scenario contrasting the knowledgeable civilised English with the uncivilised borderlands that are home to Bertilak and the other monsters that Gawain encounters. In contrast to this perception of the colonial lands, others argue that the land of Hautdesert, Bertilak's territory, has been misrepresented or ignored in modern criticism. They suggest that it is a land with its own moral agency, one that plays a central role in the story. Bonnie Lander, for example, argues that the denizens of Hautdesert are "intelligently immoral", choosing to follow certain codes and rejecting others, a position which creates a "distinction … of moral insight versus moral faith". Lander thinks that the border dwellers are more sophisticated because they do not unthinkingly embrace the chivalric codes but challenge them in a philosophical, and—in the case of Bertilak's appearance at Arthur's court—literal sense. Lander's argument about the superiority of the denizens of Hautdesert hinges on the lack of self-awareness present in Camelot, which leads to an unthinking populace that frowns on individualism. In this view, it
