This Chapter includes a debate about the republican constitutionalism as an ideal type and tradition and its alternatives. A sample of different conceptions about Chilean constitutional law is also part of this chapter including several critical analysis of some of its main representatives. Among them, we explore the decadence of republicanism in the works of Alberto Edwards and Jaime Eyzaguirre. The anti-parliamentarian presidentialism of Fernando Campos Harriet. The liberal republicanism of Gabriel Amunategui, Ricardo Donoso and Federico Gil. The alternative, marginal, social and economic order of Gabriel Salazar. The great Latin American constitutional comparison of Roberto Gargarella. Last but not least, the idea of this book is exposed. This is the idea of the Five Republics and Chilean constitutional tradition.
