Presented is a method to construct spin Hamiltonians from the R-matrix. Those Hamiltonians describe quantum spin chains where all spins interact through long-range pairwise interactions. Applications to spin-1/2 chain, higher spin chains and Zn models are given. Based on the method, the integrability of the Haldane-Shastry model and its extension is discussed.
