An alignment in archaeology refers to a co-linear arrangement of features or structures with external landmarks, in archaeoastronomy the term may refer to an alignment with an astronomically significant point or axis.

"Alignment" may also refer to circumstantial or secondary type of evidence used to infer archaeological association of archeological features, such as postholes, by virtue of their physical relationships rather than stratigraphic ones.

Types

Large scale alignments

The alignment of features on a site within or across several archaeological phases many times is an indication of a larger topology to the formation of features relating to activity in the archaeological record. Structures buildings and liner features such as ditches can all have common alignments that relate to a feature that is not exposed during excavation or is off-site. An example would be that a road has biased the alignment of features some way back from the actual road side. Another example will be contours or water courses which may be buried or obscure.

The Alignment (Hebrew: המערך, translit. HaMa'arakh) is the name of two political alliances in Israel. Each of these Alignment parties later merged into what is now the Israeli Labor Party.

The first Alignment was a 1965 alliance of Mapai and Ahdut HaAvoda. The two parties continued to exist independently, but submitted joint electoral lists. Often called the Labor Alignment, the alliance lasted three years until a merger with Rafi in 1968 created the unitary Israeli Labor Party.

The following year the Labor Party formed an alliance with Mapam, adopting the Alignment name. The two constituent parties remained separate, but with combined electoral campaigns and candidate lists. The second version of the Alignment lasted for more than two decades.

At its formation in 1969, the second Alignment had 63 of 120 Knesset seats, the only time a parliamentary group in Israel has ever held a parliamentary majority. Although their majority was lost in the 1969 elections, the 56 seats won by the Alignment remains the highest seat total won in an Israeli election.
