Explanation:

One way in which the writings of John Locke and Baron de Montesquieu are similar is that they "both supported the principle of a democratic republic." This was evident when the influence of John Locke's ideas is perceived in the Declaration of Independence while Montesquieu's can be discerned as well in the US Constitution.

Also, John Locke's ideas appear to focus on natural law, natural rights, approval of the governed in a system of government. Similarly, Montesquieu concentrated on the separation of powers and checks and balances. Both ideas form the tenets of A DEMOCRATIC REPUBLIC.
