"Discovery" is the key word.  The voyages of the age of discovery increased knowledge, brought new products, introduced cultures, opened new markets, etc.  New challenges brought changes in maritime technology - improved navigation, shipping, and associated crafts.  The expense - and potential rewards- of these complex ventures helped to spur the growth of corporate entities (there is a name for them - joint stock companies, I think, but check that for accuracy) that helped spread risk.  Insurance, too.  The huge increase in money brought about by the discovery of gold and silver in Mexico and Peru lead to major economic growth in Europe, which in turn allowed more exploration.

Booming Baby! Booming! We, in the US, were at WAR during some of that period and as with all wars fought on foreign soil, we were benefiting economically.\n\nGDP +10.32%, -4.32%, 9.77%, 5.48%, 12.99%, 7.47% for the years 1995-1900 respectively.\n\nHere is a tip though, two of the six years we were not at war.

If Germany would have known when to stop with it's expansionism, Nazism would probably still be in place.\n    Sucking up a few smaller countries just wasn't enough for the madman Hitler, he had to push his agenda of extermination of the Jews and total world conquest.

From what I remember from American history, though perhaps my memory fails, he was a very expansionistic president and he would send U.S. troops to places they shouldn't really have been. Perhaps he was the first president to give the impression of the U.S. as a sort of "bully" in this aspect, and even to day the U.S. has problems sending their troops where they don't belong. Overall though, he was one of America's finest presidents I beleive. Hey, nobody's perfect.\n\nYes, I did a quick check and that's right. He called it "New Imperialism."

Yes this was attempted in the 1800s by the American Colonization Society

C. TR thought the booming industrial growth of the late Victorian era was liable to overrun the new western territories in the name of progress and that natural wonders like the Grand Canyon could be ravaged along the way. As a lifelong hunter, rancher, bird-watcher, etc, TR wanted to make sure this newly acquired territory would endure. \n(However, as I often fight with my little brother who works in Montana hugging trees, TR wasn't against the idea of National Parks making money in theory. It wasn't so much that he wanted to put this land aside and never mess with it again. The idea of logging rights and hunting rights within National Parks was okay, so long as the ultimate control remain with the Parks Dept and not alienated or sold.)

In American history the "Gilded Age" refers to the post-Civil War and post-Reconstruction era, from 1865 to 1901, which saw unprecedented economic, territorial, industrial, and population expansion. \n\nThese links should help.

Regionally, always. Ask a native American.\nA quantum leap in our foreign policy happened in the 1890's.  But we have never had the same brand of imperialism as the classic European imperial powers.  Though we had missionaries and troops in China at the time of the Boxer Rebellion, for instance, we were in favor of open trade for all, and opposed to the economic rape practiced by the European powers and Japan, though nobody seems to have noticed at the time.  Since 1945, with the Europeans having spent themselves out of empire, and the USSR threating the world during most of that time, U.S. policy was simply to apply a Pax Americana because nobody else could.  Again and still, imperialist but with an unappreciated and very important twist.  There is, of course, a certain degree of arrogance, not to mention inelegance, in this position, but it's simply a case of the old "dirty job but somebody's got to do it" thing.

The main one I can think of is industrialization. Following the Civil War, we witnessed the birth of corporate America and the making of Getty and Rockefeller. Fortunes were made in Oil and Steel.

The Monroe Doctrine - principle of American foreign policy that initially called for an end to European intervention in the Americas, but was later extended to justify U.S. imperialism in the Western Hemisphere

Someone here mentioned 50 military actions since world war II.  For the sake of the discussion lets assume that is true.  Fifty military actions and no adding those countries to the United States.  Fifty military actions and no use of atomic weapons.  Fifty military actions and spending billions to rebuild “other” countries.  Fifty military actions and the world has an increase of democracies.  Fifty military actions and millions of people continue trying (legally and illegally) to get into the United States.  If the United States wanted a third world war, it would be raging right now with the deaths with hundreds of millions dead from atomic war with no one able to stand up to the United States.  And yet it restrains from using its massive weapons.

A few of our early leaders coined the phrase and ideology "Manifest Destiny"...look up that term to get the exact folks.  America would soon stretch from sea to shining sea.

there wasn't a huge cash economy back then, unless you're talking about cities but then was the same as now.  a house in new york in 1888 isn't going to cost the same as a house in nebraska in 1888

American History Timeline:\n\nTimeline of the Twentieth Century\n\nLinks to History Timelnes\n\nYou haven't said what kind of timeline you are looking for. If these are not helpful, I suggest you use the phrase "20th Century" instead of 1900-2000 followed by the topic and lastly the word timeline. You are more likely to get a result that way.
