Each jurisdiction has its own laws; but laws are often quite similar, arising from similar values and similar social, economic and political conditions.
There are several distinct legal traditions; these differ less in the substantive content of the law than in their jargon and procedures.
The several different levels of government each produce their own laws (though the extent to which law is centralized varies); thus at any one place there can be laws in force established at the local, state, national or international levels.
