This paper invents the notion of torified varieties: A torification of a scheme is a decomposition of the scheme into split tori. A torified variety is a reduced scheme of finite type over \documentclass[12pt]{minimal}

\begin{document}$${\mathbb Z}$$\end{document} that admits a torification. Toric varieties, split Chevalley schemes and flag varieties are examples of this type of scheme. Given a torified variety whose torification is compatible with an affine open covering, we construct a gadget in the sense of Connes–Consani and an object in the sense of Soulé and show that both are varieties over \documentclass[12pt]{minimal}
