Imperialism is the intention of one country to rule over another country: for example Great Britain wanted to gain control over India - this is an example of imperialism.
For this land is definitely needed : without a land, there is no "other" land to take over.
I would say that the other necessary aspect is people: the ruling country will need some local population to rule the country, if not only to translate and help them communicate with the local population.
The Equal Protection Clause is the correct answer.
The equal protection clause, found within the 14th amendment, has the purpose of protecting individuals' rights against discrimination.

By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
On a national basis, natural gas has long been the dominant choice for primary heating fuel in the residential sector. Lately, electricity has been gaining market share while natural gas, distillate fuel oil, kerosene, and liquefied petroleum gas (propane) have declined.
Part of the national change in heating fuel choice can be attributed to population migrations farther west and south. But even within Census regions, electricity has been gaining market share at the expense of natural gas. The Northeast is the exception, as both natural gas and electricity have been increasing while distillate fuel oil and kerosene have declined.
In the Midwest, most homes are heated by natural gas. The Midwest also has the highest percentage of homes heated by propane, although both natural gas and propane have lost market share to electricity since 2005. The South is the only Census region where electricity is the main space heating fuel in the majority of homes. Heating fuel preferences in the West largely mirror the national average, although households in the West are more likely to use wood as their primary heating fuel or to report not using heating equipment at all.
