Does morality necessarily have to be legislated?
I tend to believe that there has to be some common values shared by most people in order to live free. Things like respect for property or the rejection of violence as a means of getting what you want. I do not think these values have to extend so far as to the Judeo-Christian morality as commonly understood on this website.
As long as people do not violate the rights of others, they can be free and yet have different moral systems.
Name a modern amoral or imoral people who have been free.
Your challenge is difficult, as every people in every time have faced some restriction on their freedom. Also, by what standard do we judge morality? But, I guess I could offer Western Europe as an example. Relative to the rest of the world and to history, they are very free. True, most are social democracies and limit economic freedom in some ways, but the social democratic model has been in place there for quite some time. Compared to America, most of Western Europe has low church attendance and more relaxed views on sex and drugs.

Western Europe is a great example of a decayed and decadent libertine failure. You may embrace the eruoweenies, I emrace the values of Western Civilization that they have abandoned. If your definition of 'freedom' revolves around "more relaxed views on sex and drugs", I can only offer you my condolences and prayers.
