How did constitutionally limited government and democracy emerge in the West? Many scholars from many different perspectives have attempted to answer this question. I identify the emergence of these forms of self-government with early modern nationalism. Broadly speaking, nationalism of the right sort provides indispensable resources both for united popular resistance against autocratic rule, and for the formation and legitimation of national systems self- governance. Resistance and self-government both require a national consciousness that includes a myth of national origin, a national language, a common faith, and, crucially, native traditions of self-government, and stories of heroic ancestors who successfully defended those traditions against usurpers and tyrants. It is through national consciousness that abstract theories of resistance and self-government become concrete and tenable. It is though national fellowship that the idea of a political nation, possessing the right to make rulers accountable to its will, comes into existence and is sustained over time. My arguments basically fall under two headings, historical and theoretical. By an examination of the nationalist political thought of early modern European countries, I intend to establish important historical connections between the rise of nationalism and the emergence of self-government. But I also intend through the examination of the very same materials to emphasize that a certain set of nationalist assumptions is indispensable for making self-government coherent. The main body of the work consists of an in-depth examination of the early modern nationalist political thought of three Europeans nations, the Netherlands, England and Russia.
