The US Constitution is the oldest written constitution still in force anywhere

Evidence

The Constitution of 1787 is still very much with us. It has gone well past its two hundredth birthday, yet it has been amended only sixteen times since 1800. By now, it is by far the oldest written constitution still in force anywhere. There are countries with much longer histories, but most of them (like France) have suffered constitutional upheaval time and time again. There is no American Third Reich or Fifth Republic. There is still the first and only American republic. The Civil War was, to be sure, a major constitutional crisis, but even then, the Constitution survived (though at tremendous cost in blood). — Lawrence M. Friedman and Grant M. Hayden, American Law, 635
